I'm very skeptical about a 'cheap' machine that's suppose to do things usually reserved for major surgery and lots of dollars and coins, BUT I got this massager in early September, didn't use it regularly until the last 2 weeks of the month, mostly at night, usually on the blue with heat level. Well the right picture is Oct 1, 2024, the left side was a still picture taken from a video dated on June 2023. I'm going to keep going to see because I don't know if it's my small weight loss, the collagen I've been taking or the serum I used on my face. But we shall see.
