They say it really is comfy, not scratchy and easy to use. It stays in place well - although we had to experiment with which undies worked best for each son to keep the cup in place, since they typically wear boxers and haven't used a cup before!
They like that the outside is soft and doesn't dig in, but it was hard enough to protect my 8 year old when he got hit as catcher in machine pitch.
My older son has some sensory issues and doesn't like the textured back of the cup on his hands, *but, he does like wearing it and I think the texture helps keep it in place, so he just has to deal with it for a moment while he puts it in place. Not a problem for our younger son with no sensory issues.
We love the product, the personal service and the quick shipping!
