I wouldn’t call them great
Got these for my bf he has bad knees. The first time he wore them he burnt himself. The cords are so short your literally stuck in one position plugged into an outlet. Let’s be honest they are knee pads with a vibrator and heating coil in them. Don’t ever go over the 20 minute timer they get way to hot. If you buy with a coupon sure why not full price yeah no that’s a joke.
