I have numerous small health issues that prevented me from living my life with vim and vigor. So after I saw some interviews with Phil on the YouTube or another health channel, I thought long and hard about whether I should buy one or not. I read up and studied the health benefits of the FIR. I thought everything I read was good, so I finally took the leap. I've been using my sauna for 16 days only (although I've had it now for 24 days). So to date, I can say I love it and am happy I took the leap. Why? Well, for me, so far it's a subtle change...but definitely for the better. I seem to have an increased sense of well being, happier mood, a bit more energy, and a bit less aches and pains. My issues go back many decades so it's unreasonable to expect instant results. But I'm very happy with the progress and very happy I bought the machine. I look forward to using it every day.
