Good for racking
I have the color coded BD neutrino's and Camp Nanos, I came across this set for a good price when I was doubling up my cams. Overall I am pleased with them they are much larger and actually lighter (than the neutrinos) but I'm not sure if the price difference is worth the cost of these biners. I don't understand why camp used the straight gate's for these as a bent gate would be much better for high stress clipping on your red point.. Besides that I usually always sling my placements long which makes using these photons kind of overkill. Also being a larger caribiner these tend to make your cams hang slightly lower. I guess I'm nitpicking too much at this point. They do clip nice and I do like the color quality of them, for example the green is a much better green than what BD uses.
I would say get these if you really love clipping rope straight into the racking biner, and/or you use half ropes, and don't mind spending more. If not just go with the smaller rack packs...
