I've had my Iolite for almost a year now, and I've had pretty good success with mine. I consider it a game changer.
After 9 months, it just stopped working. I called Iolite, and after some troubleshooting they promptly RMA'd it. While I was waiting for that to arrive, I bought another one. When my replacement arrived, they threw in a extra mouthpiece. I also use the optimizer.
Maybe I just have really good herbs, but I get about 30 minutes a bowl without the optimizer, and about 20 minutes with it. I do feel like I get thicker vapor hits with the optimizer. Great tip about spinning the bowl, btw.
It's nice having 3 mouth pieces, as I often have long drives (I drive around 30K miles a year). It's nice to leave with more then one pre-loaded bowl. I read the tic-tac box method...I'm gonna try that. I like to make edibles with my Iolite poo, so I currently accumulate the abv into a mint box now.
I don't get that great run time per refill though. About 2 bowls worth, maybe. I've tried to bleed the tank out, but it's still only 2 bowls. It's not a big deal, as I just keep some butane in the trunk of my car, and at home. If need be, I've thrown the can in my pack.
I've used mine everywhere, and in retrospect, a few places I shouldn't have
. I've had limited success with it skiing however. I'm on the East Coast, so altitude isn't a problem, but the cold has been a bit of a show stopper getting it lit at times. When it works, it's a game changer for the slopes. First and foremost, herb is on the inside, so wind isn't an issue. Secondly, once it's packed and fueled, you can totally operate it with gloves on. That's pretty nice for riding the lifts. We usually toke on the lift rides up, since the runs are so short here, as opposed to a safety meeting style session.
I've had a bowl or two slide apart, I found a pretty good solution is to use one of those rubber (
livestrong style) bracelets and wrap that around the unit.
Peace
