This silicone plug has much to recommend it. The size and shape are both excellent. It is not to big but neither is it too small, and the narrow 'waist' keeps the plug in place. The silicone is very slick and comfortable and is very easy to clean. The vibrating unit packs a lovely punch, indeed it is the best vibrating anal plug I've found. So what's the problem? The three watch batteries needed for the vibrating unit are difficult to find and seem to have the life span of a fruit fly. If the vibrator is turned on and kept on, it will not last fifteen minutes. Just as one is getting into it, it dies. Terribly unfortunate, because otherwise it is really great!
The Silicone Anal Dildo is made of a firm but not hard formulation; this makes it easy to insert, but not uncomfortable in use. The shape stays in place well, making it so you don't have to worry about 'losing it' at an inappropriate time, but doesn't make it difficult to remove once you're done. I'd consider the size on the high side of Medium; not so large that a beginner can't take it, but they may need some warm up first. The most surprising find was the accompanying variable speed vibe; a small but powerful package that is remarkably quiet when in place, but is guaranteed to get attention when turned up on high.
