Anything that isn't already in the 100+ page thread? lol I doubt it. It's always good to remember that although vaping seems very similar to smoking, it's really not as simple. When all you have is a small heating element to maintain the temp, a lot of people hit/draw too hard and all that cold air coming through the bowl can lower the vaping temp, sometimes too much. The iolite is one of those vapes you have to hit with a slow, easy draw. After a couple of min. of 'on time', it'll be ready to put out some vapor (1st hit can be very tasty, I've found). After it's been on for 5-10 minutes, and assuming you have a decent amount loaded, your vapor output will increase.
A good tip for this vape is to avoid handling it by the mouthpiece. Pull the bowl off by grabbing the herb chamber (the part flush with the body), not the stem. Also remember that it'll operate differently when exposed to cold temps. It'll be cold just after loading with butane (don't start it up right away), and in cold winter weather using it outside can be a problem, depending on the temp and how long it's exposed to the cold air.
I've used mine the last couple of days. Although I also use the Launch Box, I still really like the iolite for portable use.
