Lovella Adjustable Cock Ring - Vibrating Ring Perfect for Couples - Easily Adjustable Erection Ring for Endurance and Pleasure - Black

Does not stay tight.Therefore not much use aoart from vibrator which is ok.

The round plastic clamp thing just slides back up so it doesn't go tight at all. I tried to email the customer service on the card that came with the product, the reply wasn't in England so I don't have a clue what it says.

Since I only have experience with a normal penis ring so far, I decided to try it out here, and I have to say that I am completely thrilled. It can be easily adjusted to the right size, is comfortable to wear due to its flexibility and very stimulating due to the vibrations. My partner and I are extremely satisfied and recommend it without reservation.

Bought for fun with the Mrs. Will have to wait for the right moment!
