i bought the extreme q vape extreme kit and it came with an iolite as well.. i really like the iolite, its nice and small, and it doesn't look as cheaply made as the mflb..now, i'm not saying that the mflb is cheaply made, just saying it looks like a fifth graders science project is all..
the iolite vapes well, and doesn't need to refilled all that often, maybe every two or three days or so, depending on how much you use it.. i like the way it hits as well.. the only thing i'm not crazy about with it is that it continues to make some noise even after you're done taking your hit.. its always making a bunch of hissing and what not for about 30 seconds or so after your hit... other than that, i can't really find much to bitch about on it.. i've heard that the toggle switch that you have to push in to ignite the unit tends to go bad after awhile, but i've had mine for about 8 or 9 months now, and use it pretty much every day, and it hasn't skipped a beat... i actually use the iolite more than i do the extreme q, and i really bought the package for the extreme q, but decided to go with the extreme q extreme package as it wasn't all that much more than the extreme q on its own, and it was still about half of the price of a volcano, and i got two vapes for that price..
i'm fairly sure that i got mine from amazon, and i got it in a day.. i almost shit my pants at how fast it got to me, i have to say.. i can't remember what store i got it from, i wish i did as i woud highly recommend them to anyone looking for an iolite or the extreme q, or both for that matter..
