Is the back end still hot? Ive been Using my hopper for 2 months now. other than the back End getting pretty damn hot Its preforming perfectly. But if the newer backends arent hot anymore ill send it in for warranty..
Edit.
This is for gandalf..
Some nice thai man makes them, takes him 10 min charges150 baht. I guess any guy who works with glass in the us can make them aswell.
Cools the vapor by 90% id say...
Someone wrote and i dont know exactly who that its harder to tighten the back when nearing the end, thats due to the spring on it. Try without a battery in and u will see it diasapears.
The hopper has a pretty consistent taste for some reason. Precise taste but someone has to make some kind of longer mouthpiece with a cooling element at least this is how i feel.
I wanted to know cuz mine is pretty new and heat up time to 4 from 0 is about 7 seconds i guess its faulty, but not enough for me to use the warranty just yet. Mine is gt 12xx so urs is newer.
