If you hate turtlenecks, you won't be able to strap this to your neck that tightly.
I love that this has a USB cord that's about five feet long. I can plug it into my car charger and drive with this around my neck OR put it against my lower back and it stays quite warm. Surprisingly warm, to be honest.<br />You can plug it into your computer, a charger port, or without the charger block.<br />If you are NOT a fan of things like turtlenecks, you won't want this on too tight because to secure it, you have to strap down the velcro tightly and that's a problem for me personally. I can't have the strap on too tight, and that's the best way to keep the heat against your C-spine if you can't press against something like a headrest or a cushion. That's the biggest drawback for me. I do use it against my lower back as well as the C-spine, but just beware that you have to be careful about that strap.
