$650 was way off the mark for what I paid, definitely under £100, and Amazon UK currently has them at £65.
It's also hard to believe any of the published findings of gimmicky devices like this [1]. Another paper says it doesn't provide any benefit [2], but then I question this paper, they only did 3 days. It takes me about of month of muscle training to really notice any effect. And now I feel I've already gave the POWERBreathe® too much attention then it deserves. ;)
