It's actually a good biner and does the job well. However, I feel it's too small for any long outdoor climbs. The size is the same as any quickdraw carabiner (e.g. Black diamond freewire) but with a locking mechanism. That means it's only limited to single rope belay or can only be attached to thin belay loops or gym harnesses. If bought for those purposes, the biner does a great job!
