Purchased their breathing training device during preparation for a charity run. Build quality feels solid, resistance adjustment works smoothly across levels, and the companion app guides routine progression sensibly without overwhelming complexity. Lung capacity improvements felt modest but measurable across six weeks of consistent use per my fitness tracker data. Cleaning instructions could be clearer, first deep clean took trial and error to disassemble correctly without forcing components. Price sits high against simpler breathing exercises freely available, but structured guidance helped maintain discipline where self-directed training previously faded.

Helpful lab testing with clear results

Used Farris Labs for some testing and the results came back quickly with clear explanations. The site is simple to order from and support answered a question about sample collection promptly. With only two reviews showing a good rating, I was cautious but my experience was smooth and professional. Good for straightforward lab services.
