M10

Performed excellant on vertical ice.. and w/front points adjustable you can choose your poison. Like any crampon ball up is typical but w/anti balling plates repairable. Solid sticks and stable placements

I love these crampons and from the half dozen I tried, these were my favorite in terms of feel and security. Only beef is that I can't add a heel spur, but hey climbing "bareback" seems to be the ethical direction anyways. I didn't try the BD Bionic or the G14s, but from talking to my climbing buddies, they feel that they're all about the same. I got these super cheap during a summer sale, with the anti-balling plates tossed in for free, so price wasn't a factor. I would probably have gone for the BD bionics otherwise.

Update after 5 years:
I still like these crampons and have used them for everything in the mountains imaginable in the last 5 years. I've used them for summer alpine approaches (too heavy for that really, but didn't feel like buying a second pair of crampons), heady steep ice, alpine routes, and mixed. I've climed on mono-points for the last 4 years, and I like the assymetric configuration for everything except alpine. Two horizontal frontpoints seems a lot more secure feeling, especially in Neve.

They ar heavy though, and I'm now changing the rating to a three. Since I started ice climbing 6 years ago, everything has gotten a lot lighter, and crampons are now exeption. Next ice season I will be rocking a set of Petzl's Dart crampons, which climb exactly the same way that the M10s do in mono-point configuration, and cost the same to replace the points! I may not be using the side-lock closure system that has been popular, will let you know after a couple years of abuse...

These are pretty nice crampons. The ability to shift your front point(s) around is nice.
Only complaint is the front section: it balls up really bad. The anti-balling thing should help that a lot.

I love these crampons. They ball up a bit, but which crampon doesn't? The anit-balling plates can help to minimize this, but take them off if you'll be encountering any mixed ground as they're not that durable. Would like to have a heel spur attachment. Otherwise would've given it a 5! They climb like a dream in dual or mono point setup.

Overall good crampons and versatile... BUT, lacking newer improvements like heal spure. I think, for the price, DMM Terminator are a better choice. Especially if you have semi-rigid boots.

3.5 would have been my rating...
