Hopper HT000001 checking in here

So far I've been really enjoying the IO, granted I've only had it several days. Some of the improvements are readily apparent, the back-end being one. I haven't noticed any back-end heat at all during use, and threading it onto the body is much, much smoother on the Ti model (SS was always pretty smooth for me).
Performance has been great*. Admittedly it doesn't white-wall pieces as well as some of the OG hoppers, that said, I think this is a good thing. As much as I loved getting the pieces milky I always suspected some of the OG hoppers were running too hot. For example, I owned an EQ for a while and to get the same bud to the same color the EQ would have to be at like 450-460 while those grasshoppers were supposed to max out at what, 410?? While having the option to get hotter was nice I think such wide variability was tightly tied to all the reliability issues.
Despite all this the hopper performance is still excellent. A bowl is still easily finish-able in 2 hits through a water piece if desired. While the pieces aren't fully "milked" the exhale is still quite satisfying and, like I said, the power is clearly still there. My preferred method hasn't changed from the OG, 1-2 direct hits at temp two-three and another 1-2 hits through water at temp five. Flavor is great and terpy at low temp albeit a bit dry, flavor still okay at full heat and quite a strong vape signature.
Battery life is okay. I received at GBH2 with my IO and get 3-4 bowls/charge I think, I can keep track more carefully if people are interested. In the best of my old batteries, which are 2 years old at the newest, I'd estimate I'm getting two bowls per charge. I haven't tried it with my oldest batteries yet. Hopefully the GBH3's will be better. HL said they will have new chemistry as well as just being new cells so hopefully that works out, they still owe me 3 from like 2 years ago so I'll be looking to grab those!
Although its far to early to say for certain I do get a feeling this will be much more reliable. The backend does feel like its been improved, and although the heater isn't getting as hot, which is unfortunate, I feel that this is likely an improvement in the long run as well.
Overall I'm quite happy with this hopper, if performance maintains for another 6 months I'll finally be comfortable recommending it again. Unfortunately I do have to mention one, admittedly minor, issue. The heater's screen inside the chamber keeps falling out, as in repeatedly. I've replaced it maybe 6 times over 2 days now. If this continues I'll have to follow up with HL for a solution. Its just not okay for this to happen on a brand new, top-tier vape. In their defense it would be almost impossible to detect in QA because it only falls out after several uses, but regardless its a bad look. Maybe they could have considered a design where the screen is able to lock into place? I believe the mouthpiece screen does something like that.
Happy with the vape, performance is good, battery life is decent. Outperforms anything I'm aware of on the market but it wouldn't be HL without the signature hold-up like the screen falling out. Check back in 6 months for reliability and to see if I'm still recommending it!
