In the interests of Science, I looked up: Vibratissimo Panty Buster, available from Amazon.
The one Customer Review:
too good to be true..
Unless you have android 4.4 or higher, you cannot use it. Also, the vibration was weak and the ability to connect via Bluetooth too which made it too irritating as you had to spend ages trying to make it connect. I wouldn't recommend it..
Just imagine the situation... "Connect you **** !!!!!!!!"
