Just received it, but so far so good. Like that you can use either charged without a cord or plugged in. Arm straps help with a snug fit-another similar one I had did not have the straps and it was annoying. The App controls are helpful as you can’t really see the controls easily once you are all strapped in. Got it for headaches. Not a miracle but helpful and worth it. Sadly nothing compares to human hands. But we take what we can right?
Love! Perfect massager. Actually rubs correctly not oversized or undersized. Also Great for all back and legs as well. Every person of my family has tested it and loved it.
