Works great, heats up quickly, size that came is shorter than pic, about 4'10" but a better idea since your sitting anyway, heats up amazingly fast, works way better than I expected! Don't panic like me, delivery may take several weeks.... Recommend getting a little bigger chair than the one provided, small for me at 5'10", but was fine until I changed it... Great sweat in this sauna, just like at the gym!
