I didn't feel anything! The 'action area' of the toy is so small that it just doesn't produce enough stimulation. It was a very tight fit for me, so I feel that a few exceptional men wouldn't be able to use this product.

The Robo Suck was a really good idea that Doc Johnson came up with. The design is not as well as the idea though as it does not do grip my penis, it just shakes it. This product did not do anything for me. I think this product is something the world is not ready for.

At first, I wasn't very impressed with the Robo Suck because it didn't seem to do much. Over time, I've come to enjoy it a lot more and have found that it temporarily increases both my length and girth. Although it has yet to propel me into space, it does help to pressurize my liquid fuel tanks so that my payload can be released.
