Familiarity: I've put it through the wringer
I recently had the opportunity to use these to climb and ski some Volcanoes in southern Chile - They above and beyond exceeded my already high expectations.
When I first got my hands on them, two thoughts.
1. So light. They are easily the lightest crampons I've ever known and are first class for a non-rando-competition crampon.
2. Packability. They pack down super small, they come with a really durable, but easy to pack with gloves on, carrying case. They can be folded and shoved in this bag and closed up simply. No hassle, no zippers. The bag is beefy enough where I was not worried about the points tearing holes in anything.
They handled tremendously on the boiler plate, iced up, and wind buffed flanks of Lonquimay - our volcano objective. I was able to front point, flat foot, and side step up steep bulletproof and feel totally confident.
The dyneema adjustments are super simple and easy to adjust on the fly. The first few times using the crampons the cord needed to "break in" so I made sure to put the crampons on super tight the first day - and by the end of the day they were a little loose. I tightened them just a bit more and now they fit perfectly - with zero slop.
The strap and clip are simple and easy - and kept the crampon attached to my boot the one time they did come undone while breaking in.
Thanks to Petzl, I now have zero excuses to not bring crampons and now those objectives are a little more approachable!
