Discontinued The Grasshopper

[pxl_jockey]

for me the pen form is not really important...

You’re right about the form factor: novel, compact and sleek but it’s unreliable in operation

I don’t own a hopper but have long lurked here, hoping for the time when HL would iron out the kinks and deliver the product all of you have paid for (some of you many times over). I’d love to experience a session with a properly working grasshopper because it sounds amazing but I’m becoming more & more resigned to the likelihood that day will never come. But anyway, I remember @Baron23 & others saying something to the same effect about how the persistent faults and widespread unreliability being down to the components being defined & designed around this predetermined “pen” form factor. With all of the known engineering & component issues that’s resulted in so many repeated failures consistently over years(!) now, it’s pretty obvious this is true.

And while it’s insane that HL pursued a “cart before the horse” product design, it’s even crazier that they haven’t abandoned this form factor and come up with a completely new & reliable design, where the form follows the function. To my mind that is maybe the only way this company can rehabilitate their reputation and survive. It’s madness that they continue to let a singularly flawed product define their corporate identity in the vape-world; why are they married to this design? They’ve made themselves a punchline in a long-running industry joke and there’s just no defending the way they’ve chosen and continue to choose to conduct business and behave with their customers. Seems there’s simply no trust left among the people who have supported & believed in them.

Well, that is certainly one significant factor in the criticality of their design. It also drove the absolutely idiotic decision to have a custom battery made. They also seem to have completely fucking glossed over parts interchangability and real solid testability.

These guys say that they were aerospace engineers. Well, I wouldn't want to fly on anything they designed.

Then there is the issue that they seem to have no idea how to run a business. There is absolutely NO excuse for why I got on of my GHs back from RMA in 3 months and some folks are still waiting a year to 18 months. Its my personal suspicion that Hopper just lost the fuckers. If your Hopper has been with them for a year or more, I would suggest jumping up and down on their head and demand a new one (repair by replacement, yeah) or even just demand you unit back (bet they can't find it).

One of my GH is working well now and I do enjoy it for the OG reasons I bought it....that is, the heater basically. It could be a great engine for any number of vape designs.

But the Vape Critic's GH just went cop lights....yeah, there goes yet another sensor.

I was really hoping that my 2000th post (?!?!) might be less mundane, more substantive.
Be careful what you wish for...

Yesterday a Hopper Labs battery exploded in my top dresser drawer. I don't know if it was a b1 or a b2. Almost all my batteries are several years old.
I was in a bit of a hurry, recollecting exact detail has been difficult. I do know that I had just taken the fully charged batt off the Nitecore D2 and put it into a silicone sleeve button end first (my habit, I know if they're charged or depleted according to how I've inserted them). The flat end then remains exposed in the caddy I used. I dropped the caddy into an open-top box where some accessories and stuff are 'organized' in the drawer, closed the drawer almost all the way (about an inch open) and walked toward the door. There were no other batteries in the organizer box.

Heard a loud 'pop!' (less than a firecracker, more muffled) and turned to see huge plumes of smoke coming out of the drawer, accompanied for a few seconds by a hissing sound and soon a real bad plastic-type smell. Opened the drawer and a small cardboard package containing a glass stem from another vape was on fire, though it went out soon on its' own. The glass stem inside was shattered. There was a hole melted through the silicone battery caddy and a lot of barely recognizable battery parts all over the place. Soot all over everything. I have more smoke/soot remediation to do today.

Needless to say, I was fucking freaked out. Another 10 or 20 seconds and I'd have not been in the room, might have had a much more serious situation.

I cannot think of the exact trigger. Maybe a tear in the battery's insulator/cover? The batteries only slide about halfway into the silicone sleeve, leaving the other half exposed, that's what I put in the drawer. The battery was not warm at all; room temp., as the charge had stopped much earlier.

Best regards to all here on my 2000th post and as I near my 6 year anniversary of being a member and serious Combustion Fucker.

Wow! Glad you’re ok. That is very strange. I have older batteries too however purchased in a few batches but the last ones are a couple of years old - and I just loaned 2 of them to a friend to test out his pre-order Ti which recently ‘died’ (I have a battery order since April for both us too). I’ll let him know to be careful with these though I’ve never had an exploding battery issue with Hopper batteries.

So HL gave me the usual BS response saying they now working on October (2018) units so mine shouldn’t be too much longer. Strange that I don’t see a message option when I logged into my account this morning via mobile web, perhaps to shut me up? I’ll confirm this from home later but I wanted to challenge them to see if they can prove they even have my unit. I don’t trust them any longer. Complete BS.

Happy Monday to all.

Glad to hear that didn’t go as bad as it could have! Lucky.

A tear in the plastic wouldn’t do that. The positive terminal has to short and that was in the sleeve. Are you 100% certain it was in the sleeve positive end first?

While HL is all fucked up, I don’t believe this was a fault of theirs; but rather the fault of a simple mistake.

Hopper has been in RMA since August 15, 2018. Sent them a heated message and they responded by saying that they are now servicing August 2018... I'll believe it when I see it...

Seems prices for flights are less than some folks have paid for shipping. Has anyone with a Hopper in RMA confronted these people face to face?

damn, sorry to hear! That sounds like a close call, and a bad time! Scary. Li-ion is sub-par for safety - I am not a fan of the old school tech.

How long did you have the battery on the charger? Did you remove it as soon as it finished charging?

My concern with these old batteries is that as they are all old stock (I think 2 years + at this point), the capacity is universally going to be lower than the already relatively small rating of 750mAh.

Overcharging is going to be quite easy, and using a unit that doesn't have ideal overcharge protection isn't best practice. I always recommended the Xtar MC2 for the hopper cells as I did an in-depth comparative look at the technical specifications of the recommended 3rd party option offered by HL (something from E-fest, renowned brand but with a US mains plug), the international-friendly USB powered Xtar MC2, and the much popular Nitecore D2. Of key interest is the amperage pushed post full charge detection, where the Xtar and E-fest excel with a very, very minimal current. The Nitecore D2 Charges with 0.2mA when LiIon battery is full. Xtar MC2 Charges with less than 0.005mA when LiIon battery is full. This is a considerable difference (~98%), and it really means that it is important to remove these old batteries AS SOON as the D2 says they are charged. They should not be left unattended, in that device - it will continue to charge them which is really terrible for any battery but the tolerances here are definitely questionable.

Not to assume that this is definitely the case, I am not going to claim to know the cause, but I can see that general battery safety at this point is worthy of some public scrutiny to a degree.

I did dig up this little analysis done on the GHB1's from yesteryear
https://www.reddit.com/r/GrassHoppe...per_ghb1_battery_750mah_bench_test_resultsan/

Very interesting charts, the guy who made them didn't know what the device was for, the testing is a bit arbitrary but quite insightful, it really is clear looking now that these cells are specifically designed for 45W draw. They are probably quite a volatile custom chemistry due to the power intent and from such a small package, this is why they are custom cells and you can't just expect to use any normal battery charger for custom cells. It has taken most of the life of the GH for this type of power draw to be available off the shelf (only caused by the prevailing ecig market, being much, much huger - weed industry piggy-backing has begun to happen with the likes of the TUBO etc. but again, it's slow).

Shorting or failure will cause the battery to vent, and it is basically akin to a flare going off. We do not want 18650 size cells with this chemistry anywhere near our faces, not even in our homes, definitely not in our cars. Look up the explosion size difference between different size cells, and you will undoubtedly realise that these tiny cells were your saving grace Vapviking. The bulk of the phone in your pocket is made up of safety mechanisms for the archaic bullshit we push electrons with. The batteries are much safer there than the metal cylinders used everywhere else. The Note 7 battery incident is an interesting look at what it's like without those safety measures, and it's easy to forget what we are dealing with when it comes to commercial and niche products in the modern world.

A battery that is bulging or noticeably hard to reinsert into the Grasshopper (the GH batteries should fall into place freely with no resistance) is cause for concern, as is one that isn't performing healthily. Unfortunately that is really seriously all the batteries for this device in the wild right now. They need to be handled with extra care.

Everyone should heed this warning from Vapviking and be very careful with these things.
I'm so glad it didn't go off in your grasshopper, hand, or whilst you were away dude!!

I wish this grasshopper situation would just come together already, it's really sad history. I remain very hopeful, and very satisfied with my devices, but I wish it went differently, that I could see a different situation that was happy and content instead of hard done by, deceived and smouldering.

Come to think of it, the HL fast battery charger is going to need to be scrutinised to the highest degree as they haven't done good circuitry design anywhere else, or displayed any confident or semi-confident QC and it's their most dangerous item yet... should it ever exist

I can't say that I necessarily agree with this. I do believe that they def could have used a commercially available high output battery but they were too wedded to their damn pen form factor.

But, people of good intent may well differ and that's just fine, right?

I don't know of the specifics of what was available at the time, but for sure they probably could have selected a size that was off the shelf. However it seems very hard to find something comparable even in 12650 form today.

Also, it probably would have meant using a much bigger size than 12630, probably 18650. That's too fat, it wouldn't work similarly with 18mm glass joints as the sleek 14mm PFE actually offers. Maybe it's not a bad option having a giant hopper, but it doesn't really address any of the other, more serious, problems. The battery availability is not such a concern when the device availability is as it is.
Further, using an off the shelf size means that in situations like this where HL have no OEM batteries, people would try to use any old thing and potentially run into problems. The device has avoided a lot of bulky safety componentry in favour of a solution that I've always appreciated.

I like 14mm custom glass, and have a rack of charged GHB2s next to me. They've been just fine for me, and an exquisite combo, the least of my concerns in terms of performance has been from batteries - but they better get that shipment soon!

I do wonder, if the Hopper was 50% bigger, it would no longer be ultraportable - would it still be worth the hassle?
Kind of, because of the insulated chamber and massive clouds and effect. But I mean, if it's that easy to do, why isn't there an 18650 vape that isn't meagre by comparison to a working GH.

The problem with the GH is simply the allowed tolerances and the complexity of a completely proprietary design. The battery, made by seasoned and renowned experts, is arguably the most robust part of the entire assembly. Even the body has had threading and length issues. It's not the Chinese side that is having the QC issues, it's the reality of an out of practice western world fallen behind

Thank you for your concern and your studied response. You are correct, each of us can find something to learn from this.

I'm sure this battery had been on the D2 charger for at least overnight when I removed it and put it away. It wasn't at all warm and it inserted into the sleeve smoothly (they're always a little snug in this particular caddy)

Yes, it sounded like a flare. A smoke bomb!!!
I have some 18650's and yesterday I began looking at them in a whole new light; they are huge compared to the hoppers'.

While with my case I can in no way come to a conclusion about immediate causality, I will be re-thinking the charging of all of these. It might be interesting to know "the amperage pushed post full charge detection" of the Hopper's chargers that come with the unit (I use the original and v2 of those), given the huge number of aging batteries in use in the wild.

I might be able to measure this, I have just discovered my phone can charge the GH - which is really cool!

This is why I love this shit, check out this set up:
https://imgshare.io/image/IMZg9

Yet to find a good replacement for tinypic..

Interesting to note that the magnetic charger is pulsing up to 700 mA whilst mostly sitting at 48-50mA all @5V

Swapping to a cell charged with my Xtar MC2, I managed to get several red flashes before quickly seeing blue. I have noticed it is spiking to lower currents, but it remains pushing 5V @46-48mAh whilst the lights flash blue.

Disconnecting the hopper shows a similar response to it becoming fully charged, so I don't think I can get the charge rate anything close to accurate (I have a USB-C to USB-A adapter inline using 3mAh, the magnetic charger itself pulls 40mAh or so when idle)

Taking a few tokes with the charger still connected, the pulsing dropped to 39-46mAh during the hit, then after I clicked it off it flashed red twice before on the third flash the current spiked to 944mAh, it has stayed there for several seconds every now and then, but mostly it seems the pulses coincide with the red flashes indicating charge.

This device was not designed to be left on the charger unattended, so it seems to be the best advice is to definitely avoid doing so. The batteries should never be left to charge overnight - it's best to get them off the charger as soon as they're done

Idk much of the technical stats end of this stuff. I do know your phone hopper charger thing is a thing of beauty, sorta!

Every time I put a Hopper batt in the D2 I manually select the 300mA setting. My understanding is the default is 500mA. I do understand that chargers taper off the amperage at the top end of the cycle, if that's putting it correctly.
My experience is that the hopper's usb charger is faster.

If I could find a better image host, the noisy iPad pic would still be ugly, but slightly less.
It's definitely something I'd never thought to do, but something I'm glad to know about and it should eventually come in handy.

The ideal charge rate - it does mainly depend on the cell itself, which is unknown. Could be LiCoO3 or something completely exotic. - is said to be 0.5-1C, where C is one-hour draw from the '750mAh' capacity.
Given the measured average of something like 600mAh with new GHB1s, that's 300-750mA recommended rate, which for the most part the magnetic charger is doing, though it has the capacity to do more and I have seen 900+, but always below 1A. This just happens to be the only USB-C power output I have, so I don't know how much this would change swapping to a different source.

Overally I'm surprised to see the rate of mAh being sent to the GH from my phone, I haven't found the USB magnetic charger to be super fast, it's probably about the same as my Xtar MC2 time from flat to full which does a conservative 500mA to begin with.


Another cool observation: seems a few tokes costs about 100mAh, that must be the most energy efficient of all vapes. I'd be most interested in seeing the induction/vapcap efficiency because that is probably the most similar(?) thing. 510 vapes suck juice like you wouldn't believe, if what you want to do is have powerful hits that is..

Anyone else unable to message HL directly through their warranty thread? Not sure if it’s just me or their warranty process is messed up. I’d like to think it’s the latter but highly coincidental - both on mobile web and desktop from home - after I reamed them out last week. And I sent another nasty-gram to their general support email just now with my warranty reference number. The BS (and RMA) goes on for 12 months...

Anyone else unable to message HL directly through their warranty thread? Not sure if it’s just me or their warranty process is messed up. I’d like to think it’s the latter but highly coincidental - both on mobile web and desktop from home - after I reamed them out last week. And I sent another nasty-gram to their general support email just now with my warranty reference number. The BS (and RMA) goes on for 12 months...

After a certain amount of replies you can no longer reply to a warranty thread. Stupid but it happened to me years back also.


My replacement back end is waiting for me in my mailbox right now. Don't have any pot and probably won't for a while but I'll at least test it out with some vaped weed or something when I get home from work.

Thanks! UGH!!!

I dared them to prove to me they still have my unit and haven’t lost it. Now that I’m emailing them instead of the warranty thread messaging I doubt I’ll get any answers...

Just sold my Hopper. It was new and hits like a beast. I used it for a few months then I bought a Boundless Tera and never picked it back up! Grasshopper heat up time is unbeatable, but the Tera just destroys me hard every time and it’s ready to go in 40 seconds. I know the grasshopper is going to work for a long time, but I did dread the thought of ever having to deal with their customer service warranties.

Just got home and tried my replacement back end. Hopper still does absolutely nothing. Can't say I'm surprised to be honest. Hopper Labs isn't even a joke - it's a dead meme at this point.

May I ask what you sold it for?

OMG - just got the “confirm your email” message for my RMA’d Ti. It’s been 12 friggin months and I just want a working Hopper. I hope it works better than it was!

EDIT: since I can’t write them a reply in the warranty thread I can’t choose anything or confirm my address (or whatever it is they want me to do!)

Great! Now we need to at a fucking blast proof bag to our hopper accessories with all the other shit to keep it from dying or burning our lips or fingers off

I am getting a Dreamwood glow in the mail this week, instant heatup time and very stealthy as it screws on top of your box mod, alot of different battery options because you can pick any mod, batteries can be bought from local retailers as they are standardised sizes.

It's not pen sizes but I am so fucking over that fact after becoming the master of constantly screwing of and on tops and tips of the hopper

Let's hope the glow makes it so I don't need to relay on the hopper as my portable vape

@Hjalmark you always find such cool stuff. (the vape, not so much the bag...)
I'm sure there's a box mod learning curve along with learning the Glow itself (you're a pretty smart guy), but they do look sweet, and tidy with those capsules. Have fun!

You might still want to consider one or two blast-proof bags!

Thank you for those compliments! Really brighten up my rotten day!

think I seen some other hoppernoids head over the 510 based vapes and the one fitting my needs was the glow as its based in Europe

I pretty sure I should actually get some of those bags as I have some random batteries lying around the house that I been planning to use for my DIY project

But anyway @vapviking thank you for being a part of community, there are some fantastic people here and I find fcforum is special in that way and something I never gotten from reddit
