"It’s a nice product, but when I think of the total cost plus shipping it’s a little pricey for the size and limited function. There’s not even a way to add a strap or hook if you need to attach it to something. Don’t get me wrong, it works well and keeps your temperatures sustained for extended periods of time, I just think you can get a lot more for less somewhere else."
