The metal balls on the rods inside make this toy. I continued to use it just as a dildo of sorts even after it stopped rotating because I just love the width and feeling of this toy.

I would advise against purchasing this product. Save up to buy a dual stimulator made of higher quality material. I have found dual stimulators with a shorter shaft more pleasurable then this. I did not find this toy enjoyable at all in any way.

Maybe they should have called this the Busy Butterfly instead of Fluttering Butterfly because everything about it is busy. It has lots of rotating beads, lots of functions giving you hundreds of combinations to try. The FB vibrates, pulsates, twists, rotates, is waterproof, it even arrives in a busy box with lots of pictures and info.

This item is a great toy for anyone looking for a rabbit type vibrator. With all of the different possible combination of settings, it can fit any mood you're in.

Two toys in one, lovely fluttering vibrations, very long battery life, and it is waterproof. I hope you as well enjoy this toy as much as I do.

If you have been disappointed with previous experiences, with a dual action vibrator, you need to try this one. I loved that I could really customize my experience with this one, due to the many settings! The size is great, and it hits all the right spots. I threw away my other dual action vibe, because it pales in comparison to this one. This product us made of PVC, and may contain phthalates. These use 3 AA Batteries, I would suggest getting some rechargeables!

With a plethora of intensity settings and vibration and rotation patterns, the Fluttering Butterfly can provide pleasure for most moods. The clitoral vibe's large butterfly wings allow it to hit higher placed or enlarged clits, making this a great dual action vibe for those who have previously been disappointed by this style.
