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!

A company that cares I am a big fan of Kaatsu bands and noticed a change in my muscle mass right away. I found the Kaatsu team helpful in getting me my bands and helping me figure out how to use them with lots of personal attention. Now I am excited to get started with their weekly meetups to keep learning more.

Resolution of problem There was a problem hitting and maintaining pressure that was resolved by unlocking and relocking all of the components.

I’ve been using KAATSU for 6 months or… I’ve been using KAATSU for 6 months or so. Have been incredibly impressed with the muscle gains. As a 63 year old woman, I found it time consuming to maintain muscle. With KAATSU, I’ve broken the plateau I sat at for many months. Expensive, but totally worth the money. Good customer support as well. Highly recommend.

Reconditioning must-have I’m a physician, and I am so appreciative of how much Kaatsu enabled my disabled daughter to recondition after a prolonged bed-ridden phase. To be able to “exercise” without actually exercising was life-changing for her. Thank you, Kaatsu!
