I bought a couple of different lenses but I didn't like any of them. I saw these and figured I'd try them. They're a perfect fit and just so high quality. I was surprised by how clean and clear they are. Each one individually put in a baggie of it's own. My flashlight looks even better now than with the original lens and I'm beyond happy with this purchase. Extremely good price and I have many extras in case I fudge this one up too.
