This is a great item to use while masturbating. The ridges are large enough that the feeling of it going in and out is fairly intense. Those sensitive to stimulation may find the toy too intense for them, though most will find it highly stimulating.

The toy is mostly smooth, save for the ridges themselves. The ridges provide the most satisfaction with the toy, especially when thrusting in and out. The ring base helps to keep the toy from going too deep, as well as it's a convenient handle when the item becomes slippery with lube and fluids.

Overall the design is great. The ripples create enough sensation that you can cum simply from having the toy thrusting in and out. It isn't too thick, so it should work well for almost anyone. While it is made for anal, it clearly should be able to offer a lot of vaginal stimulation as well.

I found the toy to be a great stimulator, better than most other vibrators or dildos that I've come across. One thing I did notice is that during most types of thrusting, the toy can have a tendency to squirt a bit of lube out on the exit motions. This is due primarily to the ridges and isn't really something you can avoid. So it's best to just pay attention to where you are playing with it, and expect a bit of lube splatter.

This is a silicone probe, so you have to stick with water-based lubrication. A small dollop of gel lube works great to create a slippery foamy coating along the shaft. Cleaning the toy is as simple as rinsing it in the bathroom sink, and wiping it down with toy cleaner or soap. Since it's silicone, you can also boil it, though I prefer to stick with very hot water in the sink or tub.

Storage works best with a simple plastic bag or soft cloth to wrap it in. It can fold up to an extent if space is an issue.
