This product is very easy to use. Just put the product in the box, close it and press the button. The only suggestion I have is that I would like an audible signal (like a microwave) to go off at the end of the treatment to let you know it's done and to remind you that your mask , your phone and everything else inside is the box. also really cheap. I thought these things were way more expensive.
