The Bunny is made of a firm, velvety smooth, silicone. It feels amazing to the touch. There is no texture to it really, just a bump on the top below the bunny ears. The bump isn't really discernible as far as texture goes, but it can be a nice change from the more flexible ears.
The name 'Bunny' kind of says it all as far as shape and design are concerned. It has cute little ears and a bump to indicate where a face would be. The body is just a standard barrel shaped vibrator. From base to top of the 'nose' the Bunny measures 3.5 inches long and the ears are about 1.75 inches long. The diameter is approximately .75 inches, so a little smaller than the listed specs. The size makes this a very discreet and easy to conceal vibrator but using the included stand might make it less discreet. I don't think that the size is specific to beginner or advanced. It functions as a stimulator of erogenous zones, so to me, size is irrelevant.
The Bunny has a push button control on the base. It comes with a battery (takes 1 1.5 V-1 battery) that is inserted by unscrewing the bottom and placing it inside. To turn the Bunny on, you simply press the button on the bottom. There is only one speed, so if you press the button again it will turn off. The vibrations seem to be focused in about the middle of the body of the vibrator and travel upward. This allows for a good amount of the vibrations to be felt in the tip and the ears.
The noise level is very low and can just barely be heard from under the covers. If you do get interrupted, though, it is easily turned off with the press of a button.
This performed well under water, with no leakage into the battery compartment, however the vibration strength isn't quite enough for me to enjoy in a shower in competition with the water.
Caring for the Bunny is very simple. It is made of silicone and waterproof, so you can safely wash it with warm water and anti-bacterial soap or by using a toy cleaner on it. Boiling this toy is not an option because it could damage the motor.
Storing the Bunny is also a snap with the included clear plastic stand. Keeping it in the stand keeps it from coming in contact with other silicone toys. To protect it from dust and hair, which it doesn't attract as badly as some silicones, you can cover it with a cloth bag or Ziploc.
