POWERBREATHE FOR TRAINING

Anyone see the website in UK concerning to a training for IMT & the products name is Powerbreathe Ironman. My friend in Japan sent me a link to study, this product is helpful for anyone like sport & especially for better performance after training 4 - 6 weeks, it can improve
breathing muscles more stronger & take running time much
longer in marathon. Anyone use this before for self-training with better running mark & where can I buy or check its quality ?
