Very high quality product Very high quality product, was happy to see that after unboxing and after I started using it. I've only started using it recently so will provide an update in a few weeks but there's a ton of good data supporting its effectiveness so I'm excited to see the results.

Been using Kaatsu for 5 years now Been using Kaatsu for 5 years now. Absolute life changing, health, healing and all over wellness!! EASY and CONVENIENT!! My favorite daily activity!

There is no magic pill, but there is KAATSU If you’re looking for a solution that can raise the bar to an entirely different level with your health, wellness, fitness, and performance, look no more as KAATSU is the answer. I have been into health and fitness all my life and I have never had such incredible results in such a short time. At 62 years young I have tried almost everything including running, lifting, circuit training, yoga, palates, cross fit, boxing, and MMA to name just a few. The way I feel after a KAATSU workout, the pump in the muscle, the results are unsurpassed. If you’re ready to soar to new heights and reach your full potential, then KAATSU is for you.

I love the educational Tuesday/Thursday… I love the educational Tuesday/Thursday sessions. I have the C3 and have recommended it to several friends. Kaatsu is a wonderful tool and I will continue to use it regularly expecting continued benefits. Thanks, Ruthie Fine

Brand new C4 device does countdown from :30 Brand new C4 device does not consistently count down from :30 with device set on LOW. This makes doing a workout impossible when the device ceases to function and I have to reset it and hope it won't fail again. Occasionally the device performs as expected but not always and not often. It is not dependable. For such a high price point I expect better. Furthermore, customer service seems to be non existent. I've called and left messages and no one has gotten back to me. 1/23/24 UPDATE. I just received a phone call from Kaatsu. The representative walked me through a test to diagnose the problem. One of the arm bands was leaking air which is why the compressor appeared to get stuck - the arm band couldn't inflate properly. He is sending me a new arm band. Well done!
