David Wadsworth wrote a review of Black Diamond Neutrino Carabiner on February 27, 2011
From one Limey climber to all the folks on the other side of the pond...like you I like the Neutrino: it's easy to clip and is nicely made, but what sets it apart from (too) many others is the shape - the relatively flat lower part of the 'biner makes it an excellent choice for racking gear. The almost triangular shape of most of the currently available 'biners here in the UK makes them nigh on useless for racking wired nuts. Using Neutrinos for racking wires has made a world of difference - they don't pile up on top of each other and, consequently, the wires are quick and easy to place. Top-notch gear.
