A:
The Resonating Butterfly Pump has a different material than the Butterfly Clitoral Pump...I find that the Butterfly Clitoral Pump a bit softer and keeps the suctions better. The vibration for the Resonating Butterfly Pump comes from a bullet, which takes the 3 cell batteries, so although strong, doesn't last more than 45 minutes to an hour, but it is wireless, while the Butterfly Clitoral Pump uses 2 AA Batteries, good strong powerful vibrations, but has a wire attached to it. Both are multi-speed with a twist dial.
