This was a Christmas present for my husband. He had to put it together since I couldn’t but he loved it since it was something he wanted for a long time. The installation was easy enough. However, the calf area doesn’t work. It just inflates and never contracts. I’m shorter than my husband and I can’t massage my feet because the calf section won’t let my feet touch the feet massage section. We looked for trouble shooting but couldn’t find it anywhere. Other than that he is happy and he uses it everyday.
