Works as intended and Good Quality. Fast Delivery - arrived before estimated time. Thank you very much!

I really like it, good quality.

Excellent .. With regulator for air .. Now it is necessary to prove it but it is seen that it is not bad quality... Worth it. .. Same as the mask and more comfortable and practical.

Great value for money. Works way better then I thought. It even works way better then the Aerofit which is 20 times more expensive. I think Powerbreathe is still a better product. But that’s also 15 times more expensive. If I could go back in time I would just buy this device as it’s great to train with.
