I have been reading with interest about some people on this site who have used gadgets like Powerbreathe etc.
So I did a search and tumbled on this site.
Its not an add site or anything like that, but it seems to give good comparisons between the different gadgets.
To those who have used any of these, how would you rate there performance?
I'm looking for answers from people who have given these gadgets a real hard crack.
Not just a "I tried it but put it away" answer.
People who use them constantly.
