All in all, this is a really great vibrating butt plug. The silicone is firm, in a sexy matte black that lubes up beautifully. The shape is somewhat challenging, but not too much so. Once in place it is a very filling, buzzy plug! I would highly recommend it to anyone who is looking for a bigger prostate stim toy, or an unusual and fun butt plug. It's functional, easy to take care of and very high quality, right down to the gorgeous, reusable packaging.
