My boyfriend and I love this, I do love a regular gag, but this one is perfect for those who want to see the inside of the mouth or even shove their cock inside the hole while in use. We tried that and love it even more than the average gag; he loves seeing me drool through the O-ring. He’s even watching me write this review and getting excited because he’s thinking of when we used this gag. The material is smooth and sturdy, and it is relatively easy to clean. I would also love to see a gag like this with it being flexible to see how we like that, but this one is perfect for when we want to keep my mouth forced open.
