This toy is great for solo use. Just grab some lube (non-silicone based) and go. You'll want to use a decent amount of lube with this as some of it gets "lost" in the ribs. The vibration options give you variety so each time you use it can be a new experience. Along with the vibration options, you can vary the pressure to create even more variety.

The sleeve (stroker) portion is made of a soft silicone that feels very smooth while the vibrator insert is made of plastic along with other materials. The ribs on the interior of the stroker are extremely soft and flexible but provide an excellent amount of stimulation. The outside is textured for added grip when in use. It's still a relatively smooth texture though, and I question whether it adds any additional grip.

When I first put the toy together I was somewhat annoyed with the effort it took to put the vibrator portion into the sleeve. The head of the vibrator is sort of shaped like an eggplant (thicker around the bottom and narrows as it goes up) so pushing it into the upper portion that holds it in place was difficult. Now that I've had it for some time I've learned the best way to assemble it is to fold down the silicone portion, place the vibrator on it, and then fold the silicone back up, around the vibrator. Much easier this way.

I think the general size of it is great for a variety of people. The controls should be easy to use for everyone, but users with smaller hands may have issues. In terms of penis size, I imagine this can be used by most. I say most because if you're on the thinner side and need to squeeze the sleeve while using it, you will likely lose a lot of the vibration. If have a little more girth, the sleeve is pretty flexible and should accommodate you without issues.

If you need something discreet, this is not the toy to get. I can't see someone mistaking this for anything else besides a masturbation sleeve. The manufacturer packaging isn't discreet either and features someone using the toy on themselves.

The vibrator features an eggplant-shaped head with a small controller that features a single button for operation. A single, short press of the button changes the modes while a long press turns it off. You can remove the controller from the sleeve, allowing a partner to control the toy, however, the cord is very short so not sure how easy this would be.

As with any silicone toy, do not use silicone lubricants with it. This will destroy it. You should clean all sex toys after use for hygiene purposes but especially this one. The little ribs on the inside will easily trap things. I recommend taking the vibrator out of the sleeve so you can wash the sleeve by itself. With how flexible the toy is you could submerge it in water and scrub it with your fingers quickly or use cleaning wipes or sprays found on EdenFantasys.
