Disappointing.
Had to return mine because it caused more irritation than relief. Thought it was a rolling massager, not an acupressure, so that's on me. Buttons emit an annoyingly loud sound when you press them, for no apparent reason, and aren't labeled well. I inserted my size 13 feet all the way into it and apparently pushed the max pressure button because the inflator held my feet so firmly while the painful acupressure points jabbed the bottom of my feet that I had to just turn it off to get my feet out. It was still an irritating massage that never got hot and I felt nothing on my arches when I did figure out how to use it. There seem to be many satisfied customers, but I'm certainly not one of them.
