The unit is a little expensive, but it might be worth it. Rends is also coming out with a thruster in spring 2011 called the A10 piston, I had the Rends R1 A10 Cyclone and it was amazing. Sadly the A10 cyclone broke recently
I had it for over a year and I probably used it far more than most users plus abused it a little because I can make myself last and the thing would be on for hours sometimes.If anyone knows any more info about the Som Rocket male masturbation device or more information on the Rends A10 Piston please reply, thanks
