For anyone curious about anal toys but inexperienced or afraid of pain, this anal vibrator is a great place to start. Small and smooth enough to avoid discomfort, a little KY or other lube is all it takes to get it to slide gently and comfortably in. For some, just the feeling of something holding your anal sphincter open will be turn-on enough. If you're a man, your prostate will welcome it; a woman, the vibration alone may or may not do it for you, but having it in during sex can be eye-opening. It's not just an anal toy, though. Being a vibrating toy, it could be used on any body part that's aroused by vibrations. The Mrs.' nipples and clit have both enjoyed its buzzy delights.

The Rump Shaker (small) plug is made from what feels like a slick, glassy, translucent vinyl. With lube, it's slick. It smelled strongly of vinyl at first, but it quickly faded. The controller is molded from a hard, brittle plastic, and it doesn't creak or flex, even when you're holding it in a death grip as you climax.

The broadly flared base and long, sturdy wire leading to the controller eliminate any fears that you'll ever need to make the infamous trip to the emergency room and have to explain how it got stuck up there ("Um...I fell on it?"). Very reassuring. The plug indents right before the base, which helps it stay in place without slipping out. It's about 4" long, and maybe 1" wide. The flared base is a good 2" across.

There's no disguising its true purpose though. No one's going to believe you if you tell them it's a neck massager.

The product consists of two parts: the plug/cord and the controller. The cord is permanently attached to the anal plug and uses an RCA jack to plug into the small hand-held controller. There is no vibration in the controller, only the plug. The controls are simple to use. There's a rheostat wheel that pokes out of the controller and falls readily under your thumb. You control the speed of the vibrations (fast to super-fast) with it. The vibrations aren't super powerful, but they can be intense. It's quiet outside of your body, but it's virtually silent when inside.

Being an anal toy, there's always the possibility that clean-up could be an issue, but the Rump Shaker is a joy in this department. Its super-smooth surface makes wiping it down easy and fast, and since it's non-porous, there's no place for bacteria to hide. We typically wipe it down with a paper towel and spray it with some toy cleaner. Voila! Done! We've stored the batteries in it for over 3 years and never had an issue with them running down.

Though the vibrations aren't particularly strong, they suffice. Also, by moving it around inside, either by the base or by rocking a bit when sitting on it, they can reach the right places and put a smile on your face. The Mr. finds it particularly enjoyable when climaxing. "It's just a little something extra as you reach that point, and it launches you right into a good strong orgasm."
