Have the 4 inch one. With a bit of practice slips in easily and feels great. However there is minimal neck at the base and easily slides out. Great play potential but needs to be held in place.

Awesome idea, but it slips out super easily (at least the 3 inch one does) making it very frustrating.

At first, like the other reviewer, I struggled to get this in and keep it in. After a few months of playing around, I've found that getting nice and relaxed and with just a touch of lube, it goes in and stays in great. Gives a nice full feeling without feeling like you're walking around with a little gape. I've worn this out to bars for a few drinks very comfortable and helps loosen me up for even bigger toys for deeper play.

This plug does what it says on the tin! It was difficult to get it in on its own, but was easy to do when using a small toy inside it to help give it a more rounded head for insertion. Once the toy is removed, it will leave a hollow space inside for you to look into or put things into. It was a little tough to keep it in at times and needed a hand to stop it from sticking out, but could manage on its own and left a nice stretch. The material is also sturdy enough not to collapse in on itself, and kept the hole open for a long period of time, unlike other hollow plugs that are very soft and floppy. Very happy with the quality of this product! I just wish there were even bigger sizes to play around with, I regularly check back on this site for a larger size or a new product altogether that will give a larger gape on the user!
