I just bought a Nils 6" after trying the lazer and Moras. I will highly recommend the Nils.
I have two bad shoulders one that had surgery and I was getting tired of smelling like gas. So, I started searching the sites for hand augers and seems like the Nils was the one that got the nod.
The Nils you don't have to put any pressure on the top of handles, which you can't because you use both hands simultaneously to turn, the auger just digs itself into the ice. Very easy and cuts 10" of ice in 10-15 secs, without sweating.
The Nils costs a little more but is very much worth it, not made in China, made in sSweden. Very cool design on blade which is more to replace, but there are places to get it sharpened for less.
