WOW! Doc Johnson rules! I bought the controller unit on it's own,but I can guarantee that you'll like this just for the unit. Put it on setting 4 and you'll be smiling.. Put in on setting 5 (rollercoaster) and you'll be laughing your head off - WHAT A RIDE! If there is a minus side, it's that it could do with being more powerful - a bigger bullet perhaps. But otherwise.... BUY IT! BUY IT NOW!!!
