Bests & Worsts Reviews from Amazon

Yeah, they got me. I have asthma symptoms occasionally and hate taking meds. I get a little tightening in my chest sometimes, no big deal. But, I thought I would try this product to eliminate the use on my inhaler which I very rarely use even when I get some tightness. So the concept here is to blow into it and it periodically stops the flow of your exhale to provide kind of a vibration in your chest to dislodge phlem, etc. It is supposed to create like a "machine gun" rate of vibration as you exhale, but only works if you stand on one foot and during a new moon... I have litterally gotten it to work one time, briefly. The problem is that when the device gets moist from "condensation?" the ball starts to stay in one place. Anyways this thing simply does not work. Save your money. I am your guinea pig here and now Bob's your uncle.
