A few weeks ago I purchased a Latch Key L in Las Vegas. You will see a little square imperfection in the lens. It’s where the marketing sticker sat on the lens. There’s one on the other lens too but you need to see it in an certain position or you can’t see it at all. I took it back. They replaced it. Same marks on the lenses. Home to Phoenix. Took it to another O store. We tried three other of the same model...the same mark is left on the lenses when the stickers are removed. The manager said, we clearly can’t sell these. I replaced it with a Latch Borderline.
