Overall, this is a very pleasureful vibrating masturbator that isn't too loud and can be used by hand or attached to a smooth surface.

The Sex Engine had such great possibilities. It has great suction and a nice tightness to it. However, there are some design flaws that can not be overlooked that greatly take away from the experience. You may want to save up for the other brand and skip the vibration.

This item is very nice and interesting. If you can make the suction cup work right, you can easily turn masturbation into a totally hands-free experience. The inner walls offer a tight grip around your shaft that is just stimulating enough to keep you aroused, making for a longer play session.
