This is a fun little toy. My only complaint is that I paid the suggested retail price of $23 at Freddy & Eddy's. It is not worth that. I give it 4 stars based on the Eden Fantasy price of $12-$14. As far as $23 toys go, I would give it 2 stars.

The material is in question, too. EF lists it as "jelly." Freddy & Eddy's was not sure. Screaming-O does not list it and did not respond to my email. Elsewhere I have seen it listed as "elastomer" and "silicone." It does not have the tell-tale stinkiness or stickiness of jelly so I think it is likely elastomer. It certainly has not started breaking down like jelly toys after 7 uses. Your mileage may vary. To be safe, use water based lube. We used Liquid Silk (a water based lube with a touch of silicone) and it has worked fine. I am not sure why the manufacturer makes a big deal out of the little ball being 18k gold (plated or whatever). The whole thing is covered in the jelly covering.

Battery life is stated at 30 minutes, but we have used it more than that - maybe 45 minutes to an hour total - and the battery is still strong (or as strong as a watch battery gets). The cool thing is that the battery is replaceable so, assuming that the material does not break down, you can continue to use it.

Cleaning is a breeze. Just slip the little bullet out of its covering, wash with warm water and soap, and dry.

As a cock ring - not so great. It does not delay ejaculation. If anything, it speeds him to the finish line. The material is too stretchy to work as a cock ring would and the vibe stimulates him probably more than her.

Overall, I recommend it if you are just looking for a little giggley couple fun but not if you are serious about cock ring function or a lifetime toy.

This toy needs to be looked at from multiple angles, literally. I consulted with the hubby on this review to give his and her experiences from three different positions. (It is tough being so thorough, but someone has gotta do it!!)

Missionary:
For her - The little gold ball is mere decoration. It really has no function. With a long stroke or rapid thrust, the nub-covered mini bullet gives a little tap on the clitoris. Nothing super-special but it does give a little extra push when things get heated. With a slow grind - well, that is a different story. The nubby bullet is perfectly positioned against the clitoris for a mild but steady buzz. It does not send vibrations down the shaft of the penis - it is all in the bullet.
For him - It is a steady buzz at the base of the penis but thrusting kind of cancels out the sensation. The stretchy ring does not increase hardness or delay ejaculation. He says that is "ok" though - the stimulation is very pleasant.

Cowgirl:
For her - YeeeeHaw! Straddling this toy presses the nubby bullet right into the clitoris. Again, the ball does nothing in this position. But keeping steady pressure on the bullet does cause the penis staff to vibrate slightly.
For him - I was a little surprised that this was his favorite position for using the BongO. The steady pressure increased the vibration for him and, as I said, sent vibrations down the staff of his penis.

Doggie - LISTEN UP Y'ALL. THIS IS WHAT THAT LITTLE BALL IS FOR!
For her - Oh Yeah! This is exactly what the BongO was made for. Now the nubby bullet tickles her anus for a special little treat. And that little ball swings with his thrusting to give a pretty strong tap right on the clitoris with every stroke. The stronger thrusts in this position also cause a slight, but a bit less than cowgirl, vibration along the shaft of the penis.
For him - 1 ball, 2 ball, gold ball . . . ok, no blue balls. That same strong tap that taps her clitoris with each thrust in taps his balls on every thrust out. He also got the benefit of the vibration being transferred down the shaft of the penis. This was his second favorite position for the BongO.

Solo for him - we didn't test this one, but it could certainly be used for male masturbation.
