The 50W istick is great, it really is but I sometimes have a weird issue with it. Occasionally when pulling a hit, it sort of skips in and out. What I mean by this is usually when you're pressing the power button and drawing vapor, it will be continuous thing. Sometimes with my 50W istick, it will only hit for a second, stop, then continue to hit. It's really strange. I was wondering if this happened with anyone else and if so, are there any solutions to fixing this?
