People from NASA and/or MIT must have designed it. It is the most advanced and fun rabbit vibrator I've ever had. The girth is the only tinytiny minus but not as significant as one might think.

This was actually a lot slimmer and smaller than expected but the vibrations are strong. Takes some getting used to but once you find the right angle it's actually pretty good - the fact that it's actually where the G spot is located for the tapping (how are so many others getting it wrong!) is definitely a plus. It's strong and buzzy, it did do the job BUT still needs to be a bit bigger in my opinion as its hard to get everything in the right place...
