A Warning:
I borrowed a pair of Climbing Technology Nuptse Automatic crampons at the weekend and found them to be scarily inadequate - on easy (grade 1/2) ground the front points simply sheered through perfectly good neve (this was northern cairngorms on saturday, so really good neve!)on which my G12's faired fine.
The horizontal front points are very narrow indeed and the secondary points are not long enough to dig into the snow even on low angled ground.
This seems pretty dangerous especially considering who these low priced crampons are presumably aimed at - beginners, who will most likely be climbing the easier snow routes where these crampons really fail.
Has anybody else had experience of these crampons - good or bad?

Please see the link below offering a few reasons as to why the Climbing Technology Nuptse Crampons are neither "scarily inadequate" nor "fisher price".
