I wondered if it was the short choking around a stem that's stressing the zigzags laterally. That and when you are going past a horizontal limb and the zigzag is sitting hard against it under your weight.

Still using mine and checking it. Went through the recall process with the mk1 and Jonesie was very good in contacting everyone they could.

I sent my mk1 back as I didn't want to risk an insurer denying a claim if I was using recalled equipment and it failed.

I think you have just said what all us using any type of mechanical climbing devise are saying, in that no matter how much time the manufacturers test there products every situation can't be replicated. It's only out in the field of use that it gets put through it's passes. It might be a good idea that if and when any body's zag fails they should put a small note with it when they send or take it back just explaining the process of climbing as to when they think the fault occurred? I still think it's a good piece of kit and petzl will get it right. They really can't afford not to.:thumbup:

swivel this swivel that ??

 

the ZZ failed at the weakest point

 

the point of failure is where the hole is drilled for the spring location.

 

the hole is drilled at the narrowest point of the side cheek

 

the hole should be located more toward the 6 o'clock and thicker part of the cheek

 

basic engineering principles

 

swivel, sideload, vertical axis, horizontal axis, whats all that about
