Stays in place, nice product !
Easy to use silicone rings.
Soft and stretchy and can be used at the base or behind the head of the penis
Had one of these in the past, they don't last forever but are very comfortable.
These cost a little more than the super stretchy rubbish silicone ones...but as they last 5 times as long, well worth a few extra dollars.
And they work a treat!
