Rubber Eye Guard DSW Eyepieces Review

I needed an eyecup for a monocular whose original eyecup was broken. It's not the easiest thing in the world, but this product ticks all the boxes. It takes some strength to pull it over the end of the monocular, but that's good as it won't fall off. When used it feels comfortable on my face. I only needed one, but that's okay too. They weren't expensive and now I have a spare.
