I have used the sauna everyday since I purchased it 2 months ago. I did set up two switchbots in order to start the sauna warming up before I get home from my 12-hour shifts as a nurse. I have noticed marked improvement in my sore muscles as well as clearer skin and deeper sleep. I'm very happy with the quality of this sauna. Besides the switch bots, the other thing I did was order silicone shower sealer strip from Amazon. This is something I have seen recommended for other brands of sauna to help seal in the heat around the door. With these two very inexpensive modifications this has been a perfect sauna. The ability to remove the benches and do some light stretches and yoga has been great.
