This product was designed and package via my favorite UK distributor and it is amazing.
The ZingFinger is perfect and you will see a new direction of adult vibrators following suit of this item.
Place the controller on your arm and fit in place with the strap.
Then place the finger vibrating unit on the middle finger on the outside, top of middle finger.
What happens is that the unit vibrates your middle finger and wow you cannot copy the vibrating unit of a warm finger. No mechanical piece can duplicate the feeling of human warmth.
Also since you still use your fingers for the stimulation where for sexual pleasure or just a massage, the product remains very clean as it never comes into contact with the direct part of the body.
AMAZING product.
If you ever get a chance to see one of my home parties the possibilities for this item is amazing, from oral sex for either one, to positions from doggy style, reverse cowgirl, etc and the list goes on and on.
