Query: Slimy and Gross

The L7 is fragile so I thought I try to get something to protect it. Unfortunately, this is not the product to do so. It was nice when I first put it on, but 24 hours later it was covered in dust and oil and I felt the need to wash my hands after each call. If I wanted that experience, I would have just used the pay phone at the 7-11. There's probably something better out there.
