Used it for the first time the other day. Took about 30-35 minutes to get up to 200, it is winter here. Did a full 30 minutes. Sweat like i have never sweat before. Set up was really easy. Most difficult thing was deciding where I wanted it. I have been looking at getting a sauna for years. Came across this and was sold. Couldnt beat the price and what you got. Very happy with my purchase!! Can't wait to make this a part of my workout/recovery routine.
