The cabin arrived fast. To set it up is quite straight forward. My cabin has pink zippers instead of white as on the picture but it is OK. The enclosed technical document writes 680W and it is perfectly enough for the purpose. It heats up in a few minutes and I have the same experience as in a big infra sauna cabin (except that my head and face does not sweat, although I would love to have my whole body in the warm) . I use it at 45-50C and for 45 minutes each time. I am 175cm tall and can sit straight in it but if you are over 180cm, the tent might be too short for you for comfortable sitting. I used the cabin 4 times so far and hope that it will keep working for a long time.
