I got this primarily for my top rope anchor. It's built more beefy than my BD rocklock and rated for 4 more kN. Also, I got this 'biner in the quicklock version which is great for teaching newbie friends how to belay. The spring loaded locking action takes that tiny bit of doubt out of my head. A small note is that this is difficult to open one handed, as the gate lock must first be pulled up before twisting, but as I got this to use for a top rope anchor and belaying, this is actually preferable to me.
