The Vibro Erotems Butt Plug Royal is a great design. It's flare with a smaller point at the top for easier insertion and swells to a whopping 7 1/4 inch circumference. Then, it quickly tapers down for "staying put" while playing around with sex. It has a flared base to prevent the toy from accidentally slipping all the way in your anus while using this toy. The remote is attached by a cord that is about 2 or more feet long that allows for you or your partner to control the vibrations while inserted. The control has a dial on the front of it, so one handed use is challenging unless you can turn a dial with your thumb. The vibrations are quiet enough that I didn't worry about being heard outside the bedroom door, but with the max setting you may want to run a fan to cover the noise. The lower setting is a gentle vibration that may be strong enough for some to send to the top, but as you turn the dial, the intensity turns up. I bet this would be fun to wear out and about if you could hide the control pack in your pocket. This toy is fairly quiet compared to some that I've used. I did not try this in the water as the remote is attached by a wire and would probably short is used in water. Overall, I thought the function and performance of this toy worked quite well. I'm looking forward to trying this one again.
