Kevin R.wrote a review of Black Diamond GridLock Screwgate Carabiner on December 11, 2011
I am usually one to avoid thing that are a) new and untested and b) a gimmick that isn't really needed... And yet this is one of my favorite pieces of climbing kit in years, really, what took so long. A great biner with the ATC, but I think it truly shines when using the grigri2. No cross loading, no fuss. And I even Munter'ed off of it this past fall just to see if I could. As usual BDEL got it right.
