This week, I purchased a 2-person TheraSauna. I found that the directions to assemble the sauna to be quite clear. I put the modular pieces together by myself, but I recommend that it's best to have a helper. The pieces went together very well, with a nice tight fit. The sauna was beautifully lit. The LED lights around the roof line, are very attractive. The Android controls for the sauna temperature and duration of operation are quite easy and intuitive. I enjoyed my first sauna session Thursday evening. It was very pleasant. On Saturday, my first client experienced a session. He enjoyed it immensely. He drank water before and after his session, because he knew that he would sweat a lot. He wants to add a session in the TheraSauna to his regular 2-hour massage sessions. Perfect!
