It is easy to use, i have no way to check if it is real infrared, so I have to trust in the manufacturer. At the highest setting, 80 Celsius, it take the 60 min to get me to sweat lightly, adding the foil sheet accelerate the process, still , I should feel like I’m melting and that is not the case. This sais it is a great option for budget friendly home product. Daily use to get some benefit.
