Fantastic gag, a little smaller than I expected but works wonderfully. It can be fastened tight enough that it's difficult to get out but due to the shape it is reasonabley easy at any time to spit it out if you need to communicate, which for me is a plus. You can bite it pretty hard and leave no marks which is also? A plus for me. Good gag and though out of the box it was a bit pungent all silicon can be.
