Customer Reviews

There are now a couple of reviews for this.

“I recently bought this rabbit in store and it BLEW MY MIND. I wanted something with a long length and the inflatable shaft is delightfully satisfying. The ears are extremely powerful and find it a perfect balance between the two. BEST RABBIT YET!”

“Ok so we’re all different sizes inside aren’t we. This feels huge in you when it expands, it really pushes and I liked that a LOT”

One customer comments that the length is a potential problem.  They found it to be too long because of the huge girth.  As a result they couldn’t get the ears to reach properly.


This one is a little more complex in nature so we wouldn’t recommend it for beginners. The unique selling point: the expanding shaft – may be too much for a beginner. There are also quite a few functions, which also may make a beginner feel overwhelmed.

Perfect for Experienced Users

This one is perfect for those experienced in the world of vibrators. If you want some new to add to your collection this may just fit the bill. The expanding shaft is certainly something you won’t find anywhere else.
