Review (3/5): Does the job I guess.
It's okay. Pretty much you get what you pay for. Personally wouldn't buy again. The gel had exploded when I got it. The replacement seems to be okay. But it's super uncomfortable and heavy. And to heat it up you can only do so in 30 sec increments without risking the gel exploding. In hind sight I wish I had just spent the money on a higher quality heat cap.
