There are two separate parts of this toy to discuss: the masturbation sleeve and the vibrator with controls, so I'll talk about them separately.
The vibrator is a well constructed and nicely functioning addition to the 10 function Adonis Vibrating Stroker. This is something that pleasantly surprised me because add-ons like these tend to be a little lower on the quality scale. It's made of PVC and takes two AAA batteries.
The sleeve is made out of TPR, a soft, rubbery material. On the outside are ribs all around the Adonis Vibrating Stroker, which I don't exactly understand. Throughout the inside are textured nubs that are basically a softer version of the ribs. The sleeve is 5.5 inches long and has a ring at the end to hold the vibrator. There was a slight odor when first opening the package, but it didn't last long.
Getting the whole Adonis vibrating stroker together was fairly easy to do, only taking a few moments. All you have to do is put the vibrating bullet in the stretchy ring at the top of the stroker and turn it on. Of course, you're also going to want to lube up.
I have to say that getting the stroker on is a bit of a chore. The opening is a little more narrow than the rest of it, and even for someone who isn't very large, just getting in can be a little difficult. After getting past the opening, it seemed impossible to get even 1/2 the way in, even for an average sized male. Eventually, it did go on all the way, but it wasn't at all comfortable and masturbating wasn't that easy. The worst part though is that there is no air hole. This creates a very uncomfortable and almost painful sucking feeling.
The only redeeming quality about this Adonis Vibrating Stroker is the vibrator. All of the functions are quite strong and different from each other, and even through the thick sleeve, they can be felt very well.
Cleaning is very simple. Just rinse it out after use and set up on itself to dry out completely before putting it away. If you want to wash the bullet, just remove the battery back and do the same thing. I wouldn't recommend sharing this toy though without using a bleach solution to wash it first.
