Yeah the smoothness appears to be a strong selling point. It is also a very simple device to use, maybe more than the FP.
And very little is likely to go wrong to be honest. There have been a couple of cases of the glass injector housing being broken, but it is cheap to replace, probably under the customs threshold too. But you could probably just grab an extra one or two spares when you order?
Sebastien the inventor is a really nice guy, he cares about his customers and wants to offer the best products and services.
He is expected to offer a silicone handle for the heater any time now, which will come with the unit. You may want to inquire when that will be ready?
And a lot of us got ours from Lacentralevapeur, who offer a 10% fc disount and the best price going already, although I doubt they will have the silicone heater cover until they restock after it is released.
@Carlos8400 has another solution using high temp O rings. You may have your own solution too.
For the injector stand, I use a cheap bubbler from dhgate which I dont ever use. It is perfect for it, quite sturdy, a nice height too compared to a low down glass stand. Sebastien is also expected to release a glass stand for the injector soon. I dont see I will need it for at home, but would be handy when travelling with the Ti to friend's houses where I dont need to carry a bong/bubbler- less conspicuous than carrying a bong just for the stand.
