I have one of these too, and I used it in the summer. You spray it with water to wet it and then wrap it around. So, it's too cold to use in the winter. It has more power than it looks, and I couldn't stand the intensity on level 3 or higher for long, so I used it on a lower setting. I got tired of it and stopped. I bought it to give to my brother, but he didn't want it, so it's been sitting around for about a year.
