My constant headaches that I had almost everyday disappeared after using this product for 3 days. Excellent product! The design of this product looks luxury. The fabric used for the inner part (the one that touches eyes) is really soft and nice to touch. My wife and I use this product, we have different head size, hence we need to adjust the elastic band, surprisingly it is very easy to adjust it. It is firm and made of good quality of elastic band. It is very simple to use this product. Put it one, press the power button lighlty for a few seconds, a welcome female voice is heard to welcome us, and it will start the massaging. You can use a few different modes from 5 to 15 minutes duration. A highly recommended product to those that normally have tired eyes and headaches from the tiredness.
