I think this is a highly stimulating toy. It is perfect for an exciting build-up to orgasm, or even during your orgasm. I can think of reasons why this would be a good buy for a single male or female or even a couple. Beginners might get overly stimulated from the twin humming eggs, but an advanced user will probably find it just right.

The ring is smooth on the side meant to be facing the one wearing it. The other side is covered with numerous nubs that can aid in clitoral stimulation. It can stretch fairly well and is made up of several smaller O-shaped holes in the toy itself. This lends strength to the overall design.

The overall design works rather well. It's not too difficult to figure out, and with the removable eggs, you can work out a variety of uses for the toy itself. If your groin is hairy, you can snag some hair when putting it on and remove it, but that is more of an occupational hazard than anything wrong with the toy itself.

While it's meant to be a cock ring, you could always snug it around your testicles to directly stimulate them with the vibrations.

For my part, I like toys that can be put to multiple uses. This is one of those. You can remove the eggs and stick them in another toy, possibly one you insert. This would allow you to stimulate other areas of your body.

This one doesn't neglect the ladies either. Despite being billed as a cock ring, you can easily use the eggs to stimulate your nipples and clitoris directly. The eggs are some of the strongest I've seen, and they are just perfect to use in other toys where the egg may be a bit too weak.

The only downside I have found is that the eggs use button-cap batteries of the LR44 variety. I'm not particularly fond of these since they can cost quite a lot in most stores unless you choose to get some at the local Dollar Store.
