Positive Reviews:

good crampon

very good crampon for vertical ice, and hard mixed ice climbing. these crampons aren't designed for mounteering or all around winter use. the antibots aren't the best but they r a mono with a removable heel spur, they just plain get you up the hard stuff.

great for vertical ice

closing mech comes in the way of the rear fang thus reducing rear fang's hooking effectiveness

Negative Reviews:

Antibots suck

I have 3 pairs of crampons - BD Sabertooths, Cyborgs, and these -- the BD brand by far beat these in just about every way aside from the heel spur in my opinion. I like the front point configuration versatility - but the durability of these crampons has so much to be desired.

1st time out, both anti-bots broke in different places. No - I was not using them improperly unless walking in snow and standing at the bottom of a climb on ice are considered improper. I was really disappointed.. Another note was the depth, or lack there of, because of the anti-bot and curved points. There is hardly any penetration when attempting to use these things on even ground (such as a rest when climbing, approach, etc.) To me, these crampons have the ultimate shiny ball effect - wow!! these are neat, get a pair, use them a little, and return or retire them and go back to your trusted and proven BD or Petzl favs.
