Recall for replacement: GRIGRI 2
This is info passed on to me by a Spanish reader.
If you are using the GriGri 2 it is worth a look at the issue and Petzl's answer. The article is in Spanish so you'll need to translate it. There are two different articles, one the issue and the second Petzl's response.
And there are some good pictures to help explain what the magazine found using their GG2.
From experience I have come to trust Petzl's technical staff to have the correct answer.
(thank you Giacomo)
But it never hurts to beware of any new gear issues.
