Quick n' Easy
Just got back from a week long snow camping trip and a summit with this.
Overall great design. I can't say enough how happy I am that the handle isn't round; with frozen hands you don't want to mess with finding the buttons and this solved the problem quite simply. Moved a TON of snow quick. Bigger blade is definitely worth the weight, especially if you're digging pits often. The shovel was a bit cumbersome when trying to start off the snow cave but after the initial small areas were cut this thing was a block machine.
Only downside: the blade can get roughed up relatively quick if you're digging close to the ground or rocks, so don't dig near rocks or the ground, duh.
