Eff that iolite hun, i spent boocoo bucks on one and its a piece. It worked good the first couple times, then it was all crappy. I wasnt even getting high ne more. Is personally say ur better off with a bowl or something. But it all depends on personal preferance. I've also been smoking very potent stuff for a long while, so crappy bud don't work for me and I have to have a decent amount to feel it. I thaught the iolite would b good for me but I guess not. Lol
