Ok, not great
"The cooling and heating function works fine and the quality of materials is top notch. However, it has a sizeable seam on the outside of the wrist, and there is no thermal material there. That's where my pain was, so it was not helpful for me at all. Also, there is a seam that irritates and even scratches my skin between my thumb and index finger to the point where it hurts a lot after wearing it for more than 10 minutes. I regret buying it and I wouldn't recommend, but YMMV."
