Does the job, buried alive!
After a week of constant use at the beach these anchors never complained a bit. And if they did I couldn't hear their cries of help buried a foot or two in the sand! Very happy with these anchors and I'm sure would work well in snow or on top of a granite face. Heck you even get a 5th spare one, who does that anymore!? Spare parts included for when your idiot brother decided to make a mini parachute out of one and loses it, I mean that's awesome! Anyway these are great anchors, very durable, and simple. A perfect adjective combination for those of us in the outdoor pursuits. BUY THEM!
