    Heats my sauna perfectly

    I was wanting a sauna heater that created heat more naturally than the alternatives. This has been perfect for what I was looking for. Great so far

    Really Nice Barrel Sauna

    I knew I wanted a barrel sauna but I wasn't expecting to get one this nice! I can tell the difference between this one and the other options I looked at.

    Assembly durable so far no issues

    I purchased this chair for Father's Day and I purposely waited before adding a review. It was very easy to assemble with no problems.The various speeds were great depending on your physical knee. Haven't been able to figure out the Bluetooth yet. Only issue is it doesn't get the neck and shoulders as good as I would like it to but the massage is wonderful after a hard days work. It's an excellent by we are very pleased
