I've had my kuiu bino case for two seasons. My biggest and only complaint, they DON'T keep my bino's completely protected. Today for example, they are wet (no big deal) but they fog up when wet and pine needles were on my glass. I do like the one hand operation and how tight they feel against my chest, they don't move or bounce around. They are also very light, if I had to rate them, I'd give them a 7 out of 10. If they protected 100% I'd give them a 10. Pine needles are all over the inside of my case!
