Input: I would given this unit more stars, but it’s hard to open and the directions are very vague. The directions did not even tell you how to turn on the unit. The unit stays on maybe up to five minutes then turns itself off. I’m still trying to figure this thing out and still trying to open it, which is very hard to do for me. I wish the mouth piece was a screw on, it would make it simpler to use. The rate I’m going, I’ll end up breaking it before I’ll have a chance of using it good. Wish I had found a better product, spent too much money for something that is hard to get into...

Mouth Piece is hard to take off and Instructions are Vague on how to turn on and off the Unit.
