Discontinued The Grasshopper

Does charging whilst using the device allow for repetitive back-to-back hits?
How does this thing perform whilst plugged in?

Oh nice, didn't know FedEx was an option, thought they only offered usps first class, or pay extra for usps priority...

No signature required i hope

I believe his was purchased through VapeFiend in UK.

Greetings, HopperHeads,
There has been much discussion and debate about the optimal texture/form/grind for material loaded into the Hopper. My physics background tells me that the operant word on this subject is "interface", which is the maximization of surface area exposure to the super-heated air emanating from the heat source as it passes through and around the material.

Also, since it seems that I am dusting off some parts of my brain that I don't get paid to use anymore, I would like to provide some rudimentary information on the metallurgical differentiation of stainless steel versus titanium. Forthwith,

1) Titanium has a much higher strength-to-weight ratio than stainless steel.

2) Titanium is much harder and more scratch resistant than stainless steel.

3) Titanium absorbs thermal energy at a faster rate than stainless steel, and releases thermal energy
at a faster rate than stainless steel.

Well, my brain is starting to get a cramp, so I will conclude this post. Besides, I have to go yell at some kids on my lawn.

 

[zymos]

Differing properties of metals aside, it's extremely doubtful that any of that makes an observable difference to the real life GH user.

OK- scratch resistance could, though if it is anodized, might not really be a benefit. Scratches through the color layer are going to be a lot more noticeable than scratches to either pure Ti or SS.

As far as the fineness of the grind, I'd think there would be trade offs. Finer grind does of course expose more surface area, yet in the GH can also slow down airflow.

Have many people on here from the USA ordered a hopper from vapefiend UK? Im considering.....

 

[slcbdco]

This sounds very illogical, but worth a try. For my Dabuddha it definitely works the other way.

Yeah, try it!

Works great plugged in although if the battery is totally dead it needs a little charge to work.


As for the difference between Ti and SS with respect to "heat of vapor" or "flavor" or whatever folks are saying they are "noticing" I can tell you I also "notice".

What I "notice" is that the Ti extracts faster resulting in "better" "richer" "longer lasting" flavor which, not being a sceintist can only suppose is that on margin the Ti getting to temp marginally faster makes it marginally more efficient this stripping terpenes faster resulting in actually better flavor on the SS in my opinion or at least longer lasting flavor.

Many people who try both notice a difference, not a a huge difference, like i still use my Ti more because I like the lighter feel but there is a subtle operational difference between the two. A true flavor chasing cannasuer may actually prefer the SS which is nice cus ya save 50 bucks!

I think that what he means is that VF deserve their units because they're backers, not preorders. And I think the same.

sure. no problem with that. @VapeFiend.com backed the Hopper project with quite a lot of money. and they get a lot of Hoppers. problem is when noobs ordered one unit, and now are adding 10 more for eBay sale.

Hi Zymos,
As far as noticeable performance differences between a SS and a Ti grasshopper from a metallurgical perspective, ambient temperature airflow post-draw/heat cycle will more rapidly cool a Titanium mouthpiece than a SS mouthpiece. As has been mentioned before by a beta tester dude, continuing to draw for several seconds after clicking the heat cycle off will cool the metal substantially. Yes, you are absolutely correct in assuming that an anodized titanium Hopper will scratch. Anodizing metal only adds color depth of a few microns, which is bigger than a few angstroms, but who really cares ?
As for efficacy of vaporization with respect to material grind consistency, I must adhere to my aforementioned analysis. Remember, they are called The Laws of Physics, not The Loose Suggestions/Hunches.

Peace-n-Love

i wonder... if you are doing a back-to-back hits trough a bong, when mouthpiece heat doesn't matter at all. isn't SS better that a Ti Hopper which keeps heat around that herb chamber? i mean, i do one bowl. reload while it is still hot and hit it again. Ti cooling down faster. isn't that a disadvantage for a multiple bong hits?

 

[lovecrush]

Well shit, now I'm thinking about changing my grasshopper back to regular titanium...

I would say no as the gh is a convection vape so the hot air which is so to say produced in the heating element (when you draw on the gh air from the ambient is forced trough) is extracting your herb so you do not need conduction heat (like in the pax often referred as "oven" and "herb is backed") so retaining heat is unwanted in a convection style vape I would assume...

 

[studmuffin]

Apparently, I just can't stop myself this morning. All pertinent scientific parameters being considered with respect to a perceptible/meaningful differentiation between a bong rip from a titanium versus a stainless steel Hopper is the equivalent of "picking fly shit out of the pepper".

I chose a titanium un-colored Hopper precisely because of the nature of titanium, but also because I know that anodized metal can be scratched. Perhaps future iterations of the Grasshopper will have high temperature powder coating colors (paint applied to a metal undergoing a specific electrical
charge during the painting process).

I am fucking in love with physics. WooHoo ! !

 

[lamedroid]

Yeah, try it!

Great tip, I tried a loosely packed 3/4 chamber and that was pretty good!


Will post a nice bubbly video tomorrow

In REAL LIFE usage, a person is not going to notice any performance difference caused by the different metals used in the construction of a GH. I'm not putting any weight on something a "beta tester dude" "mentioned", because that is one person's subjective opinion, and because BETA. And anyway, of course drawing air after switching off the heater cools the mouthpiece- that is going to happen whether it is SS or Ti.

Your so-called "Laws of Physics" come from sensitive measurements done under ideal conditions with carefully controlled variables. The GH has a temperature dial- we don't know if a given setting on one will give the exact same temperature on another. Right there, that's a single variable that makes any conclusion about different performances between two units extremely questionable. Here's another- how fast is someone drawing- how much air is being passed through the heater in how much time? Completely subjective and something no user has any way of quantifying.

As I said, different metals have known properties. That doesn't mean that GH built of different metals are going to noticably express those properties.
I went with Ti because I wanted a colored one- that or the lighter weight are really the only valid reasons for pick in one over the other.

@VapeFiend.com Can you confirm you guys gonna do the warranty claim and everything with GHL? I thought one would have to register at GHL to get the lifetime warranty. But that way, we had to deal with everything on our own..? Would be great to hear an official statement.

Thanks, you guys - like your service a lot and thinking about getting it from you being in the EU.

I think if it's the retail kits, whether they are sold on eBay or a retailer, it will come wilth a warranty. The way I understand it (based on the paper form given to backers of the kit from HL) each Hopper will come with a code that will register the warranty to that specific product and allow the buyer to go through Hopper Labs directly for a repair. I'm not sure if Vapefiend would even facilitate the RMA if needed.

Now having said that, if you buy from someone off Ebay who was a normal backer or you got it from a retail kit backer but they didn't give you that code you might be shit out of luck.

 

[studmuffin]

Hi Zymos, Of course, the fundamental flaw with many real-world scenarios is there does not exist an opportunity to apply the "scientific method", which is to say, a researcher is unable to run tests/trials on two identical phenomenon, save for the one variable which is being investigated. As for my analysis of the difference between a titanium and a stainless steel grasshopper, assuming that all of the pertinent parameters, such as draw veracity/duration, moisture content of the material, ambient air temperature, etcetera are reasonably consistent, titanium offers a performance improvement which is meaningful. For me. For you, specific aesthetics and mass are the most important aspects of the titanium Grasshopper.

 

[zymos]

Why have you decided that the difference is "meaningful"? Did you try both side by side? In a blind test? (Maybe you had someone hold them to your lips so you couldn't notice the difference in the weights)
If so, have you measured that the temperatures are calibrated identically on each?

I'm just seeing a lot of assumptions on your part, based on the known properties of two metals. I'm not denying that they would perform differently when all variables are controlled. I'm denying that those differences would be noticeble by a human user.

Enjoy your placebo effect though.

 

[Volteric]

If it hasn't already been raised I've noticed that you'll need to really watch the resin buildup under that mouthpiece. The thread if not continually cleaned will make the mouthpiece unable to screw on and make it prone to fall off and material dumped.

Is there any "safe" way to take apart the mouth piece for cleaning? I'm a bit OCD about cleaning my vapes and would like to keep it as clean as possible

If I remember right, you can just soak the mouthpiece in ISO.

Not enought for me, I've had vapes long enough to know that after an ISO bath the pieces need some brushing most of the time.

Same as a bong/bubbler, if you don't add some abrasive (salt) and shake, ISO itself doesn't clean it perfectly.

As I said I'm a bit OCD cleaning my vapes/glass

You just drop the entire mouthpiece in ISO. There's no need to dismantle it any further because it looks 100% brand new after you clean it.

Edit: Just saw your post above mine. I would still give it a try in ISO only because the results are SO good.

 

[hackslasher]

Havent tried with the hopper (because don't have one) but hot iso usually works well with my ud stems. Cool iso doesn't do to much for the build up. A little cleaning here amd there. But when I put it in a baggie soak it in hot water and shake it for a little ends up sparkly clean
