Overall good quality product, good air pressure, can stand for calf massage, can be used continuously. Lots to improve. Only 1 preset 20-minute program available, can't change any settings such as time or intervals. Big size fits large foot, but my 10.5 size can only massage either toe or heel simultaneously. Wish to be even bigger. The remote control is useless because it must be pointed in direct sight (like laser) and only 1 function so nothing really changeable.
