Great product with fantastic customer support I have been using my C3 bands daily for 2 months and have already seen improved muscle tone and balance. I have lower leg & feet issues which prevent me from doing a lot of walking, so this is perfect and I am excited. I am quite impressed with the level of customer support the Kaatsu team provides. This is a quality product with a dedicated team.

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.

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!

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.

Great product, equally excellent service, thanks! Kaatsu does an excellent job helping potential users understand the product and its potential benefits. Also, the order process was simple and direct. All good. My experience - and those of my friends who use the product - have matched and exceeded our expectations. Thanks!
