I purchased the Portable Ozone Steam Sauna almost 8 months ago during September 2018. I extensively use it after a session on a treadmill and afterwards cool down in the swimming pool. I took the equipment with on vacation during December 2018 since using it becomes quit addictive.
Although I eat what I like, the combination of sauna and treadmill resulted in a weight loss of approximately 18 kg over the period. My depression medication is also a thing in the past (4 months ago) and I deal much better with stress. I have not had flue since I started using the sauna and feels great in general as well as after each session.
