The Rump Shaker by Doc Johnson is a small vibrating rubber butt plug. This would be a perfect plug for beginners. It stimulates the back door area with gentle vibrations. It would be great for solo use or during couples play. I don't recommend wearing it out of the house, as it tends to slip out slowly if I even walk across the room. The nice thing about it being small and not as bulbous as other plugs is that it makes for very gentle, smooth penetration and thrusting.

It is made out of rubber and is very smooth. You can use silicone or water based lubes with rubber, but it is very porous; so to make it last longer, it is recommended that you use a condom or toy cover with each use. There was a slight sweet smell upon opening the package, but it was nothing off-putting. There isn't much of a texture to speak of, which, in the case of this toy, is probably better. It is slightly flexible, but not flimsy by any means.

When we got this toy, it was an introductory to anal play with toys, for us. It's small, and the vibration really helped with easing the awkward feeling. We bought it to put in and leave in during sex, but due to the small size, it didn't stay in very well, especially with heavy lubrication. But it worked well for thrusting. Advanced users probably wouldn't find much interest in this toy. While it was a nice introduction to anal, we have since moved on to, well, bigger and better things. Like an actual human penis, for example. So, I suppose it helped with achieving that goal, but now it doesn't do much for us during couples play.

The insertable length is about 4 inches, and the cord is about 3.5 feet. The biggest part is about 3 inches around, which is a far cry from most penises. And just like every toy that is safe for anal play, it has a flared base. This one is rectangle though, with rounded edges, and I think it's much more comfortable than the bulky round ones that most anal toys have.

When you turn the dial on the controller, it varies the intensity of the vibrations, and you can feel them throughout the whole toy. The dial turns very easily. It's kind of like your traditional vibrator. The higher you turn the knob, the higher the vibration. It doesn't have any functions other then the speed settings. Personally, I think that the vibrations really helped to ease some of the awkward or off-putting feelings, especially upon insertion and right at first. This is just me though. It's hard to say if vibrations in there are going to be everyone's bag of tricks. My husband isn't really a huge fan of it. I don't HAVE to have it, but it's nice.

The controller feels a bit flimsy and cheaply made, but the battery cover stays on well, and the dial hasn't broken yet. The toy has a slight hum to it when you turn it on, but I don't think you could hear it through a door, and when inserted, you can barely hear it at all. It is not waterproof.

As I mentioned before, putting a condom or toy cover on it would aid in keeping it cleaner, however, warm soapy water would do the trick. But don't forget, it isn't waterproof, so don't get the cord area wet.

It does tend to attract lint and dust, so I highly recommend storing it inside something that will prevent it from being your new Swiffer.

As I mentioned above, as far as couples play, it wasn't very good for inserting and leaving during intercourse. If you are laying down, say, receiving oral or something, it would stay in just fine. But not during vigorous movement such as walking or intercourse. The small size made it great for simulated anal sex. For beginners, it was a great way to get used to the sensations without having the thought in the back of your head that something was going to puncture though your intestines.

The title of this review says it all. As I sit in my computer chair, I have this plug in right now, with vibrations on full throttle, and a little bit of tingling lube on my clitoris. Using this plug for solo play, and getting myself worked up is the best use I've found for it yet. I can barely hear the vibrations, and because I'm sitting, I don't have to worry about it slipping out, and there is nice, firm pressure. It feels great! As a matter of fact, it's getting a bit hard to type...
