Amazing product to leave in during the day. By the time you get home, your ready to have sex all night long. This ring/massager is made of silicone like finish and is very easy to clean up. The only negative aspect of this toy is that all men are shaped differently and thus wouldn’t be able to use it as others might. You can leave it in all day without problems. I put both my balls and penis inside the ring and if it becomes to tight, just simply remove it for a few minutes, and you're ready to go again. Would highly recommend this product. Some may find the head to be a bit big, but a little work and practice will make it comfortable to insert.
