Even there is a tech-note "not for pothiling", when this carabiner is used in dusty enviroments, the lock breaks. If sand or dust gets into the slit of lock's pier, it easly comes out his place and the lock doesn't works. This is a dangerous situation.
I have sin this issue in six diferent carabiners (4normal, 2screwgate) in this 8 months. Sold in Bilbao (Spain) in 2017-2018, in "Decathlon", witn serial number 008317
I am sorry to hear that the Simond Rocky D-Shaped Carabiner did not meet your expectations. This particular model is not designed for Potholing but we do have items specifically for Potholing and Canyoning on the link below.
Once again I am sorry that the Rock D-Shaped Carabiner did not meet your expectations.
