I've been using my housemates hopper over the last few days. The lucky bastard has again got a really good unit (his other is stuck in limbo but was a scorching beast with nearly 2 years under its belt), the new one is the same age as mine, a 4/20 HT, it gets darker ABV than mine and milks up something proper. Mine is a bit cooler, but otherwise works similar. Running 2x hoppers with a claisen is so damn good, it really does a good job - adds airflow, adds punch.
There is a small noticeable, visible difference between cloud density between the units, but I'm happy with either. Mine is tastier and still does the job. Adding kief bridges the cloud gap too.
I do wish I could achieve the same dark brown, deplete ABV. I may send it in one day for a tune up, but so far after 16 weeks, it's showing no signs of slowing down. It's always run 'cool', but I'm content that it's reaching 210°C. I'd prefer 225°C, and surely the super dark brown units are hitting that sweet spot.
If I cared about consuming ABV, then a cool runner is the better option by far. But I am not one to consume ABV. I actually have a literal fuck ton of the stuff... lol
I'm sublimated, so it's worth saying that the Sublimator is on another level yet again. I mean, do yourselves a favour and get one. It's a whole different experience, and man is it good. I'd go as far to say that it is unobtainable in any practical portable form factor, true flower dabs.
I don't think much will deliver more than the GH in the portable space.. not until aerogel insulation or some such. The hopper is nearly in that space already though...
The GH is super portable and is heaps better than the TUBOx or the StemPod, both of which are really nice too.
It's hard to say, but having a solid desktop has probably been good for my hoppers life. Subliminal Sublime times.
Device reliability, calibration and critical failures are the main aspects of hopper life, but the convenience is priceless when it's there.
It's not a lot bigger than a small glass dabber... coolest gadget and a glass heads best friend most of the time
