One of my 2 CU also developed many cracks on it. Even in the pit where the glass bowl go. Still functional and only cosmetic damages but I stopped using it after reading a post here that it could get worse. My older cooling unit has a stronger CU material (or weaker magnet?). You can tell...

There's a lot of different ways you can use this vaporizer. Lately I use it as a 100% convection vaporizer by placing my screen very high above the heater (with my glass bowl). It doesn't have to be that high for it to work but I also like the efficiency of using a small load. I use an...

What part of it has cracked? The CU, bottom part?

That's when you put the glass MP in the direct path position above the bowl and heater. That way you get resin build-up only in the glass MP but you have to use a screen on the grommet to filter out the herb particles as you draw (if you hit the unit native). I've tried both but I usually...

I've had my nano for more than 3 years. Still going strong. I keep mine powered on most of the time at around 6.2. Making subtle change in temp depending on the material and my tastes. I don't reduce the temp while I'm not using it, always ready to be used. Still very happy with the...

He also did something similar with the Air Vape XS:

I have a question for people who have new gh or new rma. How warm or hot is your back-end? Is it cold, warm or too hot to touch, etc? I'm asking this because my backend is very hot, too hot to touch comfortably (gh offered to check if it's too hot or not) and this gives me shorter battery...

I have mine since august '16. Hot back-end and short lifespan for the original battery too. The new batteries solved the issue of short lifespan (my back-end still gets pretty hot, esp at the end of a battery). One time I had the cop lights a couples of times in a row (even after changing...

I feel there's nothing like the Grasshopper at the moment in the market. The choice of on-demand convection portable is limited and this one is small, easy to use (even first timers can use it), stealthy with has a 5 seconds heat up time, etc. I still recommend it because I didn't have any...

Unless I missed it, I think you're the first confirmed "iso bath" repair. I will definitely try the iso bath as a last resort before sending my gh in. I would basically have nothing to lose. You just have to be extra careful about the electronics and waiting for the hopper to completely dry...

When I received cop lights it was not right after a iso cleaning. I had a 1 or 2 sessions with it and a day passed before getting cop lights. After changing batteries and doing some dry clean up a couple of times. It seems pulling very hard on the unit (with mouth piece off) did the trick or...

Now can anybody who's tried the body dipping "up to the air intake holes" report back to us? :science: Maybe I would do it if I had cop lights and no amount of pulling and blowing while the hopper is on make it work again. I like the idea of doing a thorough clean up (even if you have to...

Ok, you win. :p I was hoping somebody would still have those instructions somewhere. It's a bit reassuring to me that hopper labs thought it was completely fine to submerge the grasshopper up to the air holes. The graph above means that by design, they didn't mind iso above the screen and...

It would cool if you could unscrew the screens by design to do a complete clean up. Especially the heater screens (since you can already dip the mouthpiece side in iso for a pretty thorough clean up). There's always going to be some ABV (and melted trichomes) trapped in there and that place...

Was it up to the air intake holes or up to the indentation line (below the holes)? While it seems there's a danger of iso dripping down to the electronic and sensor (esp if not done correctly). It shows Hopper labs were also concerned about abv getting trapped under the screen. I'm also...

I'm usually not a cloud chaser. Even if from time to time, I go for large hits. I usually prefer multiple dense hits instead. I'm still with the mflb mentality that vapor exhaled is vapor wasted. But even when you prefer smaller draws, it's much better to have a vaporizer producing thick...

@kbrown5523 I have mine since august and never had to returned it but it has a very hot backend and my battery last one bowl, maybe 10 hits. I also don't use it as my daily driver. I use my E-Nano because I feel it's more efficient for small quantity of herb (denser hits, more control over my...

First, lets say I have my hopper for almost 3 months now and I'm enjoying it. I didn't warranty it yet. This last few days I use it at around 4.5, 3/4 full of herb. Less temp stepping than usual. I never use the stock charger anymore because an external charger is more convenient for me. I...

The UM20 is not a new version of the D4. It's a different model with different features. For exemple, the D2/D4 (new version) can be used with more types of batteries and can be optimized for use with small capacity batteries (like the gh, it seems the um20 can too). I think you must still...

I tried this with a fresh battery and a random silicone whip laying around[8]. Wow, those are some powerful cool hits. I didn't realize how much vapor i took until I exhaled a giant cloud. I usually exhale slowly and I was like "there's still vapor left!?!". I think some came out of my ears...
