    I think the backend is very sensitive to any kind of patina forming on it. When I change the battery I just swap the top with some alcohol before putting the new battery in. I'm thinking of getting maybe the smallest deb of brasso to clean the contact, but I want to do more research into what that could do to the connection.

    at one point HL came out and said something about sanding/scouring the brass contact on the back-end.. I guess I'll look it up on their blogs..

    Maintenance:

    There are a few maintenance checks that should be performed every month.

    1. Keep your battery contact clean. If there is any dirt or build up on the battery contact, we suggest using a dry toothbrush to clean it. You may also do a light scrubbing with 600 grit sandpaper shine the surface. This will help keep good contact with your battery, increasing efficiency.

    Super bummed. Tried the trick this morning and nothing but cops lights. No debris in the oven so its done.. oh well

    Got the grasshopper blues



    Edit: to top it off my grasshopper feeder came in the mail from Israel... Too bad I can't use it now haha.. also o had my hopper in a 3d printed case. So accessories thought to maintain the life and I got 5 months and a few days with my pristine maintained hopper. Bummer

    sorry, random thought aftrer the last few posts talking about patina forming on the battery and/or contact.

    Has anyone ever used deoxit? There are a few versions of it. I remember buying this stuff with one of my old mechanical ecig mods. It helps prevent arching which leads to the black marks, which drops performance.

    A small bottle can seem kind of expensive, but you use extremely little every so often after cleaning the contacts.

    The use of Deoxit was discussed often and at length much earlier in this thread. Folks were using it to clean the threads on the back end and the body. It seems like it fell out of favor quickly. I think that HL may have advised against it.

    Does anyone think that maybe it's just screwing and unscrewing the back end that may be changing the way the Hopper works? Some users have posted that they adjust how tightly the back end is screwed on and the Hopper starts working better. I've tried unscrewing and removing the back end each time I fill the chamber and it seems to help a little. I know that when my oldest SS Hopper starts "acting up" (takes a long time to get blue lights, weaker hits) I will unscrew and remove the back end, screw it back on, and it goes to blue in under 5 seconds.

    I'm thinking about getting some thermal paste for the barrel terminal. Just put some on the button (tiny bit) I've noticed the golden contact film is now silver ? Any one try this? I used to bake Mac book gpu chips and add thermal paste to"reflow" the chip.. worked so maybe it will be similiar



    [​IMG]
    Come on 6 dollar fix! 99.9% silver
    ... didn't have any laying around so I'll come back in a few days and let you know if it's working again. :shrug:


    FuckRMA


    Edit : @Foghorn I think it does have something to do with the twisting of the battery against terminals. In my case at least

    So I sent my 2.25 year old preorder Ti in for its first warranty service (RMA) on 9/17 via USPS with tracking, and I received confirmation via USPS it arrived at Hopper Labs on 9/20. Never received any confirmation from HL nor did I expect to. On a whim I logged into my Hopper account just now to see if there's any activity and sure enough there was: it said my Hopper was received 10/1. I greatly dispute that but it goes to show they're so underwater they don't have time to administratively do anything right. And I'm not expecting any message from them soon nor will I nag them for a few more weeks because, reading many of the posts herein from the last few weeks after somewhat lurking for some time and originally following this thread from pages 160-250 - I won't hold my breath. Well, I will using another device - lol!

    Following another thread recently from inception with the launch of a new unit in their product line, emailing them directly and getting a rapid response on a product question on their new product, and seeing them informatively post and respond to questions within that thread is like a night-and-day comparison of customer service to HL. And their return rate with their previously released product is less than 1% according to them, not just someone saying it. I don't think HL stacks up but the Hopper is great when it works. When it works...

    It makes complete sense that unscrewing and rescrewing changes the connection. It's no longer talked about, but they designed the GH without any wires. All of the connections matter a lot for it to operate at it's top ability. Each connection except the nose (pfe or tip) is an electrical connection as are the body connections to the heater. It's an incredible design that isn't able to be manufactured consistently.

    Love it when it works, which in my case hasn't been frequently enough to bother with. I may send them both back in and wait for the best.

    this is pretty interesting to me. I'm not familiar with the "reflow" of the Mac GPUs.. what do you mean?
    To me, reflow with a SMD component is referring to flux assisted hot rework.

    I use AS5 on my Noctua D14, actually I think I used Noctua's blend last remount.
    I washed some thermal paste off and ended up burning it, it was thrown amongst some paper rubbish. Fun fact, it went up like a sparkler.

    But, I can't think of any safe use for thermal paste with a Grasshopper. It is conductive, so you won't want any seeping onto the PCBs as it could easily cause shorts.

    I second this

    Arctic Silver ARCTIC SILVER 5 Thermally conductive paste 8.9 W/mK 3.5 g Max. temperature: 130 °C.

    Which is only 266 degrees fahrenheit.

    To be honest I'm just trying things .. the connection is shorting somewhere so I figured if I'm concentrating the connection back to the positive terminal in the battery it won't divert and go somewhere else..


    By all means If anyone has info on disassembly or fixes other then iso and compressed air ... Two things that I've ruled out as issues .... And I'm not too sure that's the reason for people hoppers working and breaking after extended grinding of the battery against the terminals.

    I started getting cop lights and turning the backend until the connection was strong seemed to be the only way it worked. Noe it looks like the connection down the body is all silver with whatever coating they used around the very edge of the terminal I don't see any other issues besides that ? So what else could it be ??

    Also I would think if the positive terminal on the battery doesn't get that hot it should be ok?

    I wouldn't try it personally. The last thing you need is something exploding in your hand / face. Just seems like a bad idea. That's just me.

    I was so excited for this vape, but now I’m throwing in the towel. I’ve had similar issues like everyone else but I’m tired of the games. The cherry on top is after I requested a refund for the case that I’ve been waiting 3 years for, support is cryptic and unhelpful. No idea how the refund is getting processed and it’s been 3 weeks at this point. Buyer beware for real on this one.

    Yeah I don't think thermal paste is the ticket. It's meant for thermal dissipation and has limited practicality beyond pyromania and chip thermal management.

    De-oxit might be worth a try?
    If you push in the button most of the way and twist it, is there a lot of spring tension? The problem is there's just too many small parts, and lots of juju. Very hard to know what to recommend. Cop lights are the worst Hopper issue.

    I've just heard back that I should be 10 days away from getting my Dec 28th arrival RMA units sent back.
    I was told 20-30 days 45 days ago, so things are closing in.
    Looking forward to having a bunch to compare. I'll be lending one and rocking two units, if all goes well.

    If I'm not mistaken, all of their transactions are via Paypal. I had ordered a couple of cases -- the new style, ordered earlier this year when the 35%-off sale was on. Then I found out that a PFE fitted Hopper won't fit, so I emailed support and requested my $ back. They did acknowledge my request, but I had to remind them a couple of weeks later that I had not received the refund. Next day, it was posted to my Paypal account.

    That fact that you - and me and many of us - need to remind them means they are indeed underwater and overwhelmed. See my previous post about logging the return and receipt of my Ti RMA. The jury rests with their overall customer service experience... :peace::leaf:

    Yes, they have been overwhelmed (they admit it themselves!) but I don't know about underwater. It's painfully clear that they have made some really tough, really unorthodox business decisions about how to keep the company afloat. Like, limiting the amount of human resource they will apply to warranty work; they've decided that, to survive (hopefully eventually thrive) they have to prioritize new units ahead of repairs. Whether we like it or not! It further pisses off folks who expect different behavior. The only thing that's to their credit in these strategies is the fact that they are not dead yet.

    I think it's also very possible that some self-imposed financial rules are hampering their refund process, too, something like, "We will only issue return of funds once per month, and only after being reminded."

    As far as the recording of 'date received' of a Hopper into their system, I had a similar experience to yours, upon sending one in a couple of months ago. I could see via USPS tracking that Hopper had landed about 3 days after I posted it. Then, it took about 2 weeks for it to be posted on website as 'received'. Okay, 'Date Received' may not be an accurate column header but, in other times, they were much more efficient with this log and so this heading was appropriate. They just haven't changed the language (to "Date Entered in System"). Given the fact that we all know the service itself will take almost forever, does it make any difference? Only in the customer's comfort level. I was able to get over it very quickly, just took some patience, which has been one of the main watch-words of Hopper ownership.

    Many folks, understandably, have become very frustrated by HL's practices. Especially newer customers (folks other than pre-orders) who may not want to be on the beta-test train, they just want the satisfaction that all good money-spending capitalists deserve. My perspective is still that of one who has been supporting some young folks' vision to launch a very, very cool vaporizer. The money I laid out initially was definitely discretionary capital and I assumed at the outset this was a very risky venture. So, I am actually pleased that HL is still in business at all, and I am still hopping. Not to say that I agree with all the funky 'business practices', but I do give them a lot of latitude, in the hopes they'll survive.

    Well said! I'm not enamored of HL's customer service and, again, the fact that many older, i.e. pre-order, units as well as some newer ones have had issues and have gone in for RMA, leaves a lot on the table. I do understand they're a relatively new company and only have one main product under their belt - not sure if Stainless vs. Titanium truly counts as the same or different - however their methods that you alluded to are indeed unconventional and their monthly newsletter info is vague, cryptic at times and more of the same month after month (two steps forward and 1.5 steps back). And the RMA cataloging - a few folks herein have claimed their units have been lost or mixed up with others at HL - and administrative/customer service deficiencies is emblematic of an immature business model, one that exemplifies bumbling operations and carelessness in execution, spanning assembly, quality control and customer success.

    I'm not entirely bashing them, only giving them a good ribbing which they still need to drive home many of our points. To your point that they've not invested heavily in warranty manpower is a bit disappointing and an admission they have problems and certainly would drain any revenue regardless whether their profitable or not at this point. That their still in business is a good sign but I don't think they're doing that well given the sample size of this thread (I've posted earlier on this too). Sure there are many units that work but there are also many in RMA and folks still having issues with their units (posted herein).

    BTW, even we pre-order folks (myself included) are capitalists too spending (hopefully) discretionary funds on vapor devices. Pending getting back my Ti (GT3xxx) in working order sometime down the road, I will only spend money on HL for batteries. Their accessories don't appeal to me or lure me in any further. They need to grow up, mature and hopefully can launch a 2.0 version or another product down the road and learn from their experiences.

    Peace. :peace:

    After 1 week update:

    I have been using the Hoppper all week since I got it. I have barely used anything else except for my Mighty when I was passing it back and forth with some friends. I have used it on 2 - 5 for different things. Works amazing on my glass, and is giving me perfect hits on 3 with no cooling.

    1. Back end stays cool.
    2. ABV is even and cooked every time.
    3. Heating time is fast and consistent.
    4. Blue lights flicker when I inhale, but the way it coincides with the clicking of the heater, it makes me think that the lights are actually just an indicator of the heater getting power.

    So over all, no issues what so ever. I have used 3 different batteries, charging with the cable and with my nitecore charger. Mixing every different possible situation that I could think of. Spent an entire day with it in my pocket. Vaped an entire bowl back to back to back, no problems. I can’t think of any other situations to put it in to test it out. It has performed perfectly and reliably all week with no indications that there is any issue whatsoever.

    There is hope for the V5 bodies my friends. There is hope.

    Ok, unlike @mario - I've had my hopper since September 24th. The beginning was amazing. No issues. Very hot. Awesome.

    However, these past few days, it does not feel like it's getting as hot as it should be. Maybe it's me... but I just feel its not working the same. I'm going to try the sandpaper to clean the backend. I do think it's something with the backend as there are now black marks on the back end, and when I first got it, it was completely clean.

    We will see.

    I don't disagree with just about anything said in these posts....but would like to point out that this is the same stuff we have been talking about with Hopper Labs for what....almost two years.

    Sorry, but they have had many chances to recognize their errors and reboot....matter of fact, they have claimed to have sort of rebooted their process at least twice (and yes, this time it will really fix the issues.....NOT) and yet after 5 months of waiting for an RMA, I still have two GH that run too cool.

    Although you make reasonable observations, they seem like excuses more than reason at this point.

    Personally, I don't want to hear a fucking thing from them...I want to see CHANGE and that hasn't happened in any significant and observable way yet. Talk is cheap....

    @Baron23 Hey - I agree with you! I'm semi bashing HL here without getting angry or using any foul language. They need a swift kick if you know what I mean. My pre-order Ti just went in for it's first RMA although it should've gone in the beginning of the year or perhaps last year (but that was more out of necessity since it was my only vape - that has thankfully since changed hence, finally, sending it in). Now it's in RMA purgatory, like yours, and I'm a bit anxious to see if it will really be fixed. I don't know, I just don't know and hold out some hope but I won't be surprised if it's not as good as new when I get it back. Again, hearing all the RMA horror stories and even newer owners on this thread still complaining, leaves me cold and doubtful.

    I however do want to hear from them - about my RMA! But I won't hold my breath or nag them for a while since I know they're backlogged on RMAs. It's a shame really but there's not much we can do. Unless you count reading their hollow monthly newsletter, which I've been doing for 2.5 years. Sigh. :peace:

    At least I'm contributing to this thread which I hadn't until recently (I've been a LONG time lurker).

    I couldn't help but get onboard here and chime in...

    I've been very rarely on here ever since I surrendered to buying at least 2 hoppers... Before that, I would get Hopper Withdrawal Syndrome and you all would talk me off the ledge.

    But even as I continue to manage to keep 2 hoppers running everyday (one that works shitty, the other that seems to have more heat than it should. Meanwhile, two friends who bought one on my recommendation each had failures within the first month, and they are still waiting now for over 5 months for them to come back. It also gives me anxiety about losing my own hoppers. I don't want to feel that way anymore!:ugh:

    Coincidentally (?), I recently discovered that the oils for vape pens are available in a lot of different strains...
    I know next to nothing about these products, but I'm reading up. There are cartridges that have no additives (if you can find a medical care provider, bingo), and I've seen like 23 strain labels. And each cartridge is labeled with the breakdown ratio. I know I must be stating the obvious to many here, sorry, don't wanna sound like a newb, but I'm quite naive on regarding this type of the cannabis experience.

    If this all checks out, and I can truly obtain strain-based, non-additive oils, then I may outgrow my need for daily use of the Hopper... maybe even completely if the high is as full-spectrum as using flower. I do love the flower.

    The use of DeToxit is completely the RIGHT thing to do. HL did not "not recommend" it, though I'm sure they didn't "recommend" it either. Nor did they have a problem with Blue-Tac. I still use both of these items. DeToxit maybe monthly, and Blue-tac on the battery threads every time I replace a battery. Easy Breezy.

    On unscrewing and screwing the backend... I've witnessed this "apparent" thing myself, and I do think that the tightness and smoothness of the fitted threads is extremely important. This junction is THE only connection the battery has to complete the circuit. You will invariably notice a hotter back end when this connection isn't well-made.

    Is this a conductive grease? or a THERMAL grease? It can't be a thermal grease... Thermal grease is not necessarily conductive. Nonetheless, I definitely don't recommend this... This topic had been addressed back in the DeToxit days of conversation, like over a year plus.... Do not gunk the threads with anything. Keep them clean, and use Detoxit. You won't get a better connection.
