At least the batteries are only $7 each.@Vapor_Eyes that trouble shooting guide is really helpful. The part about the batteries life span is interesting...100-200 cycles can come pretty quickly if you use the hopper the way I do perhaps I need some new batts...and also perhaps this is other folks issue as well if they steem roll the hopper as I do and also also perhaps this is how HL plans to supplement their lifetime warranty requests...
550mAH recharge rate is totally fine, although slower is always better for battery longevity. I always try to charge at 300mAH when I remember to switch my Nitecore (default is 500mAH)
Yes in the USA. In Europe you can't get batteries at the moment, and they cost 14,5 €. My 5 batteries just live for 2 months. Means, I need every two month 5 new batteries.At least the batteries are only $7 each.
Oh, crap.Well that was fast... I guess now I'm feeling the full hopper labs experience: my grasshopper is combusting even on temperature 3 after showing some red and blue lights flashing. Warranty request created, now my wait begins (again).
Here's another example of why we could use a dedicated grasshopper fixes thread! Thanks!!!Finally for the first time took a qtip dipped in iso and did a quick few swipes on both back end threads and got some black gunk. Definitey some kind of machinery grease I assume. Probably known by some of you already, but I recommend for everyone to do this first thing upon receiving your hoppers.
Can I suggest a "Grasshopper Fixes" thread? Maybe added to Resources? At a minimum, we could put this important fix, and the video of how to tighten the mouthpiece screen.
This is great info and too easily buried in this long thread. It would be great if all fixes were easily available just a click away. Just a thought...
What happened to the Fix thread? One minute there's a new room for Fixes and the next it seems to link back to the main GH room... ??

Multiple threads for the same device would lead to confusion and a management nightmare for the moderators. We have an alternate solution: collect the fixes and make a Resource. Of course this requires that someone adopt the problem and manage it.
This morning I tried to use it and for my surprise, no flashing red and blue lights and rattling noises, and it is producing delicious vapor like it should.
Maybe it's fixed? My warranty request it's still open and I can't add a new message, since I already posted 2 things in it.
Had same experience ended up getting a new body under warranty. Wasn't till I already tried the new body and was cleaning up the old one to send in did I notice it was working.
I email GHL and was told old body might be ok. Since only had one battery at time requested if I could return body after received new batteries.
Once batteries arrived spent about a week with both bodies. I ran muti bowls at different temps on both. I found no difference in performances.
Ended up keeping the original body in the end. The new one was more of a shiny metal and didn't match the tip and backend as well.
It has been running fine the last month. Can run it at 5 thru water and can't combust. Guess a test would be to run it at high if combust again it's a issue. Also guess could try starting at 1 and trying slowly move up the dial see if different temperatures. I would think if sensor was shot it be stuck on high.
High five bro! You just saved my GH.Perhaps there is some debris in the temp dial gap that got shifted around. I would keep working the temp dial if I were you.
I was the one who posted that fix. What worked for me was moving the temp dial very fast from min to max. You might want to try going faster until it feels smooth.
If that doesn't work I would remove the backend and clean the gap with isopropyl alcohol.
I also had a backend that was getting warmer over time. It was not yet to the point of being what I would call hot.Still absolutely love the GH. My back end has been getting hotter and hotter over time. I am a one pull and done user...and I click it off before finishing...always. Still..the back end seems hotter than the heater end during a 15 second use. I notice absolutely zero functional deficiencies....the GH seems to work perfectly despite the heat generated at the back. The back end is borderline too hot to hold...especially if grasped firmly. Though subjective, it would be hard to call this back end heat "warm"...its hot...and once the button is pushed...you can feel it heat up like a stove coil.
I sent GH a warranty request and they VERY quickly sent a new back end which I should receive in the mail today. I couldn't have expected such a quick response from any company...the service was very quick and very easy. I'll report back after I receive and try out the new back end.
No complaints...my GH never stopped truly functioning ...and a supposed repair is on the way. I am then instructed to ship the back end to Hopper...which will cost me only a few dollars. If the new back end provides remedy...I'll be calling this the easiest warranty repair ever.
Edit: Ha...just got it in the mail. Quick test...just heated it up on 3, 4, and 5 without material in the chamber while grasping the back end....no heat. Yippeee!! I freaking love this thing.
I found that very interesting, especially the part about the temp dial. Thanks for posting it.
My backend has slowly been getting warmer the past week or two. It's more noticeable on one of my two batteries. It's not "hot" yet, so I didn't think it was broken and figured I'd wait till I get my preorder if I chose to do anything about it.
I had a half used chamber in my Grasshopper while I was reading that post, so I didn't want to mess with iso obviously.
I decided to just try moving the temp dial back and forth as mentioned in the Reddit post you quoted. I held the clip with one hand and rotated the temp dial very fast between minimum and maximum. The movement smoothed out while I did this. I probably did that for 5-10 seconds, and then set it back to 4, my usual temp setting.
I was amazed to find that the backend is no longer getting warm. On my "bad" battery it does get a tiny bit warm, but it's barely perceptible. On the good battery it is as cool as a room temperature Grasshopper.
My guess is there was some lint or dust or grease in there. It looked clean but due to the nature of the hopper's electrical connections even a tiny speck of dust could potentially cause issues. I use the leather sleeve which leaves the dial exposed, and I also always recharge externally, so I unscrew the backend a lot. A little maintenance is to be expected, but it was way easier to fix than I expected.
It could be a coincidence but it's worth a try at least for anyone with a hot backend. I should note that my backend never felt hot enough to burn me, but it was gradually getting warmer as the days went by.
You're right! I just tried it lol. It does feel cooler, also as I was hitting it unscrewed I then tightened it and it felt more harsh. I will keep trying it this way.When the cap on a titanium grasshopper remains a bit loose, unscrewed a turn or two, performance improves.
The tip stays cooler.
The vapor stream is cooler.
Extraction efficiency improves.
All are subtle effects. Because the threading is so narrow not much air can get thru between cap and body threads especially when tightened, but the cap is slightly larger in diameter on this grasshopper and allows air to go between cap and body threading rather than through the narrow thread channels. Unscrewing the cap a bit then opens this fresh air pathway.
Much like the vapman mixes in fresh air with vapor and same with an mflb when mixing fresh with vapor on the draw, the extraction improves due to the air stream stabilization from mixing the two air streams.
My 5 batteries just live for 2 months. Means, I need every two month 5 new batteries.

I know a few others mentioned it in the past, but last night I was playing around with some of my Silicon tubing and found it works GREAT as a whip for the hopper - takes a bit of effort to insert the hopper, but I'm getting huge clouds, and my lips aren't burning!
Now I need to dig for a nice glass mouthpiece to pair with the whip
I can't help but wonder how many of the warranty claims for backends were just for a dirty backend. Don't get me wrong, I'm sure there are defective backends out there, but I think the number may be much smaller than it seems.Y'know, if I had anything to do with GHL, I'd have a product forum right on the GH website; monitored, of course, for BS. Their flow-chart is pretty good, no doubt, but these gems coming up on here like @Vapor_Eyes Fix need to be made findable. Hell, it might even make GH's life easier with less warranty claims!
I also had a backend that was getting warmer over time. It was not yet to the point of being what I would call hot.
Thanks to a post by @GreenHopper I discovered a potential fix. What I did was hold the clip with one hand while rapidly moving the temp dial from minimum to maximum. I moved it as fast as I could for 5-10 seconds. The movement got smoother as I did this. I did this with the Grasshopper turned off.
I actually did this in the middle of a chamber, between hits. The next hit the backend stayed completely cool, I'm talking room temperature. That is how my hopper worked for the first few weeks.
If your new backend gradually gets hotter you might want to try this fix. Here's my original post with a little more detail:
