For many years sex toy companies have been trying to find the thing that will revolutionize performance. Looking for something unique that will feel different, look different and be different. Now the Stronic line is that, rather than vibrating, they pulse, which means they more or less thrust themselves inside of you. Instead of a rotating motor, they have a weight that moves back and forth, doing all of the work involved in using a penetrating toy for you and making the pulses really rumbly. Experience the Stronic difference from fun factory sex toys.
