My favorite quality is the power in this package and it runs smooth and quiet. It worked so well, at the end both of us were shaking. The strong vibrations set off some amazing fireworks of pure pleasure! It is very fun to use with a partner but is just as good to use alone. You are in for an amazing time! If you really want to get this moving, add a harness into the mix, it will make it to where the wearer doesn’t get worn out trying to keep it in place. The clean up is also easy.
