This tool saved us from having to return a toy that we thought would not work for us. Thank goodness I did some research before sending one great dong back! This product is great.

I think that for the purchase price, it was worth the buy. Made well for its purpose, it could have done to be a little more padded.

The Vac-u-lock Plug is a replacement part for the Doc Johnson Vac-u-lock harness system. This plug can be used with any toy in the Vac-u-lock line and it snaps securely into the Vac-u-lock series harnesses, holding the toy and harness firmly in place. While not much of a toy on its own, this plug is absolutely invaluable to making the Vac-u-lock system work, and it never hurts to have a spare.

This is a basic plug for those who already have a harness, as it does not come with one. If you are a fan of strap on sex, the Vac-u-lock system is one of the best in my opinion.
