Works great once you figure it out!!
I was very skeptical at first about this working, but it does! I'm still figuring out what placement works best for me and what intensity setting, but it's going well so far. It doesn't instantly block pain for me but gradually does over a few minutes, but that could be an error on my part. The sensation was definitely something to get used to, especially when increasing the intensity. It's not bad just surprising for a second! If you like using heating pads, this has a similar feel to one, just not the same kind of "heat" sensation.
