Overall Review: The Chair was very easy to assemble and with minutes I was sitting in and enjoying my first of many massages. The first time was a little uncomfortable at first. It has a timer that last 15 min. I did notice that the second and third massages were very pleasant. You do have to get use to a deep muscle massage. I now use the chair three times a week for 15min. And find it very relaxing and refreshing. I would recommend it. I also recommend giving it a few tries to get your body used to it. last but not least the blue tooth speakers paired instantly with my IPhone XR and with the right music I did feel the 15min was not long enough, so I pushed a few buttons to change it up and enjoyed a second round.
