All I have to say is WOW!!! Great product and definatly packs a punch. Use it on her and then put it at the base of the shaft on the man and tell him to hold on. I could start a small earthquake with the vibrations from this little purple animal. Best part of it, it takes two AA batteries instead of the hearing aid batteries. It was our first purchase and it was well worth it. If you are hesitant about what to get, just click add to cart and you wont be dissapointed. One con is that the cord isnt extremely long and the on/off knob is hard to find if your occupied. But both are small prices to pay for such a incredible feeling. WOW
