The big Vibrator Just was not very powerful for my wife. But I turned it over and she liked the little one. That would be the only reason I'd give you the 3 star.

I'm a very average size man and thus product is a bit too tight.
I liked the earlier version bettet.

Weak and batteries dont last very long

Keeps cutting off, then 1 1 works and the other doesn't

Both bullets on this toy are incredibly strong! While they are only one-speed bullets, they will not disappoint. It took me a little bit to figure out how to get it working, and here's what I've discovered:
1. The top (longer) bullet should come with the batteries pre-installed. You will just need to remove a paper spacer between the batteries and cap. Turn it on and off by pressing the button once.
2. The bottom bullet should be ready to go when taken out of the package. Just press the button on the bottom of this bullet to turn it on and off.

This isn't my toy but I will give you guys for stars and thank you so much for the free gift. I haven't had a chance to try it.

First step: lots of lube!!! The rubber is a little thicker than other rings so if he has any hair, it won't be so pleasant without a little lube!
Vibrations were powerful, but subtle. Having the vibrators on both sides of the ring was knee weakening! Definitely recommend!
