Any good? Worth the £16.48 plus postage?
Quite correct. Just like a mouthpice - you stick the thing in your mouth and so have the same concern (or lack thereof) regarding cleaning the thing.I don't see what's 'awful' about it, any more than any other 'exercise device'?

They simply restrict(to an adjustable degree) the airflow through your mouth so you have to blow/suck a bit harder, thereby exercising the muscles, etc, involved in the breathing process.
It's no worse to use than blowing up a balloon...not at all like emphysema (I assume that was a joke?) which must be a very frightening and unpleasant condition, because you cannot simply 'turn it off'.
BTW, I am not an agent for these devices
I just think they probably have some merit ...like a Bullworker, Swiss Ball or exercise bands.
