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!

I bought the C3 in June I bought the C3 in June. In Oct. the connector on the leg band stopped working. After many communications they sent a new one. Then in January, I realized the leg bands were not inflating properly. Turns out one was leaking at the seam. For a product of this cost there should be a longer warranty than 6 months. Customer service was poor.

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!

Able to exercise when otherwise impossible After an illness, I was able to use KAATSU to increase muscle mass when a dangerously low blood oxygen level would normally have prevented any exercise. In a short amount of time, muscle mass and blood oxygen saturation returned to normal.

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.
