Having heard about the health benefit of infrared sauna's, I decided to look out for one. This one was recommended by Jonathan Landsman and I have not been disappointed. The operation is very simple and the temperature gets really very hot, which makes me feel happy to keep my head outside of the sauna tent, although I sometimes put it partially in for a few minutes. Earlier I had a sauna sleeping bag from another company, but it was pressing heavy on my body and I sent it back. Really happy with this one, which feels and works so infinitely better!
