As someone who's constantly been disappointed by gags I was overjoyed with this product! I'm a small person with a little mouth and always find gags (ballgags especially) too large to be comfortable; sometimes they don't fit at all! Beyond that having something to bite down on added a great aspect to the whole event. It didn't hurt my jaw or make me feel as if I'd snap my teeth off! It was perfect for what we needed it for and it's easily become my favorite gag.
