This is my favorite biner (perhaps because I can't afford the Wild Country Heliums). I talk about how nice this biner is on basically every climb. It's just awesome. It actually makes me happy when I clip with it. Where to begin? The gate opening is large, and the gate action is incredibly easy and smooth—so much better than the BD Neutrinos. I wish this came in different colors, I'd be happy to rack with these as well. For draws they're excellent; they're super easy to clip into gear/bolts/chains/whatever. The nose is basically keylock—it is extremely rare for it to catch on anything. If you can't afford the amazing Heliums, then the Nitro's are definitely the nicest 2nd option. In fact, you could save your money, get these and still be totally happy.

I have 2 or 3 lockers on my rack. This is always one of them. It's a great biner that doesn't take up too much room and has a pretty large gate opening that works easily for any anchor/power point. It spins pretty well with 7 spins up and about 5 spins down with gravity. I'd be willing to use this as a belay biner; I'm sure it could do a munter, and it handles clove hitches like a charm. Basically, it holds whatever I need to fit into it, and is happy about it.
