only problem with the launch box is longevity of use.. it does for sure give you a thick ass hit of vapor after only about 10 seconds, but after a minute the battery dies and you have to recharge it. if you wanted to take it out with you all day, or heaven forbid on a camping trip, you'd need 50 lbs. of batteries. Iolite runs on a little butane, one fill will let you vape for about 2 hours.
I do see vapor in my exhale from the iolite, but not always. the flavor lets you know you're getting the vapor. try just using it first thing in the morning, and don't smoke anything else all day other than the Iolite. see how you feel
