Overall good buy
Good for pregnancy back and leg aches. Got this because I have a bad hip from a car accident that happened at the beginning of my pregnancy paired w sciatica that got unbearable during pregnancy. Decent product for the price..i don't recommend applying directly to skin. Fabric in between makes it more comfortable to use. Red lights come on when in heat mode. The lights on mine started to flicker after about 10uses. Not sure if that also means the heating mechanism is going in and out or not. But overall has helped me get some sleep on several occasions. I like that I can use it on my legs, lower back, neck bc it can be positioned to do so.
