The Aneros Peridise comes in a set of four ABS plastic anal probes. To use the Peridise you start with the biggest size and work your way down to the smallest size, gaining control over your muscles and achieving a greater amount of pleasure. You lube up a probe and put the tip in and let your anal muscles pull the toy up inside you. Then your muscles are supposed to move it up and down inside you. You could also use them like any other probe for manual stimulation which feels really nice.

The Peridise is made of ABS plastic. The material can be sterilized and it's of good quality. It is smooth for the most part, though some of mine had imperfections and weren't completely seamless. Not being seamless doesn't effect use, I just expected better quality control from a well known company such as Aneros.

The Peridise is designed to work with your sphincter muscles as a hands-free toy. The tip is very good for penetration. There are two bumps on the shaft separated by a smooth portion to stimulate the muscles. There is a nice stopper/handle so it doesn't go too far. The sizes of the Peridise are really small compared to most toys, and they easily stay inside you.

I have used the Peridise for a month off and on, and tried every size at least once. I have yet to experience my muscles moving it in and out. I can use my PC muscles to get some enjoyment — other than that they work okay as a probes. They stay in really nicely so you can use them as plugs.

The Peridise are very easy to take care of: just wash with soap and water when you're done using them. If you want to share them with a partner you can use bleach to sterilize them and be safe. They come in a very nice cardboard box with a magnetic latch, and a place for each of them. That makes them very easy to store, which I love in a toy.

They come in a cardboard box with a cardboard slip that goes over it. They box is amazing — it has a magnetic latch and has a plastic insert with a place for each toy. In the box there are a few instructions for how to prepare the toy for use, and things like that.

I've wanted the Peridise for about a year and decided to pick it up. I heard amazing things about it, but I have to say all the amazing things I've heard made my experience not live up to my expectations. I wanted to feel the toy go in and out on its own and have the intense and powerful orgasms I've heard about. I'm aware this sort of thing may take a long time before I'm able to experience it or my body may be different and I might not ever experience it. I will more than likely be making a follow up review if I am ever able to experience it, or if I decide it's not going to happen.
