I've owned several other models by this brand and this basically replaces all of them. There's suction, there's stroking, rotation and vibration all in one unit. It can be a bit overwhelming. USB C charging makes is a nice convenient improvement over older models. This is quite a bargain over other brands. Other brands charge an arm and a leg for the visual realism and textured sleeve in addition to a separate purchase of a large, bulky, loud and expensive stroker machines.
