I was skeptical at first, but after using Powerbreathe altitude & environmental systems for a few months, I can confidently say that it's worth every penny. The device is easy to use and the results are noticeable. I have seen improvements in my breathing capacity and endurance. The customer service provided by Powerbreathe was also very helpful and responsive. Overall, I am satisfied with my purchase.
