Fantasic item.

 from East Wenatchee, WA– Verified Buyer

This works great, I use it for my seat belt. I am short and it keeps the belt from cutting my neck. I have had others like this and they would move some what this is smaller and dose not move on the belt at all. I was hit head on a couple of years ago and not having one of these the seat belt almost cut my right breast off from the impacted. Know the belt is right were it should be between them on my breast plate, which is tougher part of the body.
