I needed some new tubing for my peep, and this was the only product on the shelf that didn't include another peep. I bought it not realizing it was silicone based until I got home. When I attached it to my peep, it was so slippery that it would slide right off the peep stem unless there was almost no tension on it. There weren't any instructions on the packaging, so I tried some alcohol to make it less slick, but nothing worked. I'm sure the goal was to make something that didn't dry out and crack like the rubber tube does, but I found the stuff unusable and returned it. Ultimately I bought an over sized peep that didn't use tubing.
