    Guys....you should know by now that I do own a GH, it has not failed in a bit over 18 months, I believe, and I love the performance.

    But @Mr. Gweilo 420 does make a very valid point....if it doesn't function then it matters not what feature and performance it may have under optimum conditions. If it doesn't work, it may as well be a brick.

    FAR too many failures and and embarrassing history of failed RMA repairs (either didn't work when returned to customer or failed very quickly thereafter).

    IMO, there is no excuse for this (and please don't cite the form factor....if they couldn't make a vape that functioned consistently in that form factor, then that form factor was a design error).

    So, they say that they have retooled production and test processes and procedures, updated sub-assembly design, etc in order to improve their abysmal reliability and testability.

    At this point I don't think there is anything productive to do except observe over time and see if these improvements were in fact realized.

    Cheers

    Since when do calculators have cameras? Much less old calculators!

    But I still like it:brow:

    I've been advocating an 18650 powered GH (specifically a 510 threaded atomizer) for ages. The fact is the 18650 is a proven system, reliable enough to power a car (Tesla)

    I haven't had a GH in a while but as far as portable vapes go mine was basically a one hitter. I just couldn't get on with a portable vape where I always needed to bring spare batteries. An 18650 can be had with 5x the capacity of a GHB but is not nearly 5x the size. It's just a no brainer IMO! Their 3D printed spiral heater is a winner, but they are crippling it with underperforming proprietary battery formats.

    Its not the battery that is the problem
    I personally thing that it's the fact that there are literally less then millimeters between components

    I feel like the problem is that we are basically vaping through am expensive mechanical wrist clock that ends up seizing up the gears with residue

    Feel like the tolerance are so small that it makes the design hard to perfect

    Though they have shown they can improve battery life and even how hot the device outside can get

    Though I can't see them improve smoothness without redesigning the pen like front end completely

    That's why it's the perfect vape for me AFTER compensating for its weaknesses

    1. Own other vapes
    2. Vape through something (drip tip enough for me)
    3. Multiple batteries


    Edit: in the end the hopper can vape like a +300 dollar "click a button" plug-in vaporizers and that is why everyone is hanging on to it even though you had negative experiences with failure and hopper labs return time

    I'm all for their heater tech in different forms.
    But even if the GH was 510 threaded, it'd still stop working until they properly suss out their system issues.
    When a hopper stops, it's battery is still properly functional, it is just the electrical components and potentially the heater itself causing the vast majority of RMAs.

    I've experienced the hopper getting 4-5 bowls comfortably with one 750mAh cell. So the cell can sustain the 45W draw comfortably for ~0.6g of Herb, which is leagues ahead of alternatives considering efficiency.
    Sure that's rare, but they should be able to solidify those figures if they can attain some proper QA.
    Their chemistry is specifically tuned to high drain service, not so with the Panasonic's NCR18650Bs you're referencing; they have a nominal voltage of 3.6 V and a discharge end voltage at 2.5 V.
    It's just no good.
    If the hopper had 18650s, they'd have to be a specific type, like with S&Bs Mighty/Crafty or the Ghost, who just opted for sealed properitary options at a high cost.
    The only reason 18650s are so affordable is because of intense quantity being produced. However there are many, many variations of an 18650 cylinder cell - the 18650 is literally just a size, and if the hopper is actually working properly, it's not really needed as a personal device.

    If I recall correctly, a member of this forum modified their GH to incorporate 4 18650s in series and managed to get ~100 chambers, 15g, from 1 charge.
    He ran into issues as his electrics added too much noise to the PWM circuitry and it was no good long term.
    This is pretty much the issue they're having, they're having fluctuations at either end of their boards due to wear and tear, and that mucks up the algorithms until the device will not function.

    When the algorithms are functioning properly, the device is efficient with battery power.
    But ultimately, a couple of batteries take up the space of an arguably needed cooling device. It's still ultra portable, but not perfect.

    It'll be interesting to see what they offer in terms of power accessories. Their '3-batteries in 15 mins BC' is a good example that they can potentially offer amazing things with the latest USB type C interface.

    That's the whole idea of the 510 atomizer, so the majority of electrical systems can instead be implemented by other manufacturers with more reliable quality control systems and established electrical engineering.
    IMO this goes way deeper than batteries. The 18650 is just a good idea. But what do I know, honestly I'm surprised people are still so hung up on this one, I guess mine never worked well enough for it to be hard to get over.


    Mine never got 5 bowls with one charge. More like one. I recognize the 18650 is just a size, I'm no expert, though I used to be sponsored by A123, so I understand battery technology at least decently. I've never used an NCR18650B but it's a low drain cell. There's nothing I own that I would run that battery in.

    True. Though it's only been since the GH launched that box mods have had temperature/auxillary feedback loops, since the nicotine ejuice heads have prompted such large scale production to arrive at the feature being standardised.
    It's given rise to the Splinter and Tubo Evic, but sure, the GHs heater and insulation would be upgrades for either design.

    Yeah, most hoppers haven't been their true potential. If they can manage to deliver it, it might be worth revisiting.
    Otherwise I'm with you and will move on to the Splinter.

    For me the potential of a HL atomizer lies in the possibility of providing a high wattage heater in an atomizer that's under 22mm diameter.

    I'm inline for a splinter and I'm excited about it but I'd love a convection dry herb atomizer that could fit on a side-by-side mod like the Smoant Knight.

    I know I'm in dreamland here and this is purely a hypothetical wish that probably doesn't in anyway align with HL's roadmap.

    They seem to take the apple school of proprietary development so I doubt they intend to go into a more open design pattern like the mod/atomizer market.

    But hey you can't stop me dreaming :myday:

    IMO the hoppers past problems have something to do with oil and resin and bud dust that gets in the heater and other components. You can’t pull it apart to clean properly. Things get all gunked up inside.

    They have different trucks all the time but there are a few Arepa trucks and I usually hit those up https://therayback.com/

    Is GHL part of the "Ratpack Collective"? Some kind of "nomen est omen"? ;)

    Guess who's hopper gave them the munchies :rolleyes:

    Unfortunately the best I can hope for is something like this:

    So I'll stick to my hopper and home made sandwiches.

    FWIW if you really are getting 5 bowls per GH battery, I don't think the 18650 convection portables are really getting more than that; at least a single 18650 based design. Though I do love the idea of a 510 threaded GH atomizer if it could potentially be switched about from fixed internal battery mods (ultra compact) to multi cell 2-4x 18650 mods for home use. Super versatile. I feel similar about Splinter vs Zion. It's definitely cool that you can run the Splinter on a single cell mod, or a 4 cell mod, for capacity bested by even the Flagship Zion.

    Not sure if this is old news but HL is now directing people to blow out their hopper with compressed air if they're getting a temp sensor issue. I know it's been a user suggestion for quite a while now but I had never actually seen HL say to do it until now.

    Where are they asking customers to blow the compressed air? Can you provide specifics? I'm getting intermittent cop lights, even with new batteries, but eventually it still ends up working after adjusting the dial back and forth a bit.

    Into the herb chamber and LED holes. Not sure if cop lights are temp sensor or not but worth a shot. I have a weird thing with my dial too where if I don't twist it back and forth it will flash blue, more heat will build up at the back end, and it won't produce much vapor. A couple back and forths on the back end and boom working like it should. Weirdest thing.

    Imteresting that this is an official recommendation.
    A couple pages back I had mentioned some other cleaning techniques to you. The 'soak in alcohol up-to-the-airholes was, I believe, from a HL suggestion a couple of years ago. (I know, years?!). We had had some, though a limited number of, stories of this working.

    Your problem could also be a connectivity issue. Turning the clicker also turns the battery contact to which it's attached (on the back end), so you might look at that (and the contact down inside Hopper while you're at it) an give it a quick clean. Cleaning contacts on the batteries themselves might also help. For the contact on the back end itself, I believe it's also been suggested that you can refresh the surface by rubbing it very briefly with a piece of 600 grit emery paper.

    As I mention all this, I'm also reminded that keeping back end treads clean (both male and female) helps keep good battery connectivity. Folks use Blu-tac for that. I use one called Stik-tac, a similar product made by, I believe, 3M.

    Be careful with canned air. It almost all has a bitterant in there to keep people from trying to breath the stuff (which is right up there on incomprehensibility for me with eating Tide Pods? Why would you do either of these things??)
