Review on Ultimate Shiatsu Foot Massager with Heat - Electric Feet Massager for Pain Relief & Circulation - Adjustable Deep Kneading, Rolling, Air Compression - Remote Included - Fits Men Up To Size 12 by Travis Kjar

It took me a minute to adjust the setting as nowhere on the device or in the documentation does it say what color is light, medium or strong. Thus, green appears to signify light intensity. . yellow medium and red strong. But it's intense, so maybe too much for the elderly and sensitive. It is painful and pleasant at the same time. Constant rolling can make the area sensitive. Since your leg is pinned, you cannot lift it for relief, you must fully straighten. The rolling pressure under my toes is great and I love the pressure just wish there was more. the top of the foot. Unless you have a strong tolerance, you CANNOT do this twice or every day - like I said, constant rolling in one area can make the foot sensitive. I'm stressed out for at least 10 of the 15 minutes I put on the timer lol. Enjoy
