My favorite part of this massager is that it’s wireless, unless many other massagers out there. It comes with 2 gel patches that can connect to the main body in case you want to use it on others places as well. The heating function is great as it actually gets much warmer than I expected; I only had to use the low or medium setting. There’s a button to cycle through the 6 different massage modes, and the color indicator changes based on which mode you choose. I wish that the instructions listed which color corresponds with which mode, but unfortunately it does not, so you just have to try each and see. It would also be nice if there’s a timer option, as the default is 15 minutes and can’t be adjusted. Although there could be some improvements, overall the massager serves its purpose well so I’m satisfied with it.
