Works as directed, can go on the shaft or on over the balls. The ring feels firm but comfortable. However, you really should make sure it's the right-sized ring for you. It's 1-inch diameter un-stretched and if you're closer to 2 inches in diameter, I'd say it's going to be a little too tight. I'd say the right size to fit on would be 1.5 in diameter.

The feel is nice and thick so it's not moving around too much and grabbing pubic hairs. If you put some lube on the cock ring, you don't feel like it's so slippery that you can't work with it.
