Here are the pros and cons on this chin strap.
Pro: Simple design, single strap, slender. With thicker designs, you can end up sweating depending how hot you get during the night.
Cons: Like any chin strap, it will leave marks on your face depending on how tight you have it on. It might slip off your head if you tend to toss and turn a lot at night making it ineffective. Easy to clean since there is not a lot of material.
Overall, I like it. With time you start getting used to it. I've tried a couple of other chin strap and this one does far is the most comfortable and easy to use.
