I bought a pair of used GoreTex Crocodile Gaiters for $40 before October elk hunt from Geartrade. Both gaiters experienced catastrophic failures with the stirrup buckle post breaking off both of them. We were able to tape and bind them to get through the hunt.
When we got back, I contacted OR, and they had me submit a warranty claim. OR had me send them pictures of the gaiters and asked me to put a huge "X" on both of them with Sharpee and send a pic to confirm. Upon receipt of the pictures and claim, they promptly issue me OR store credit for $87 to cover the full price plus shipping of a brand new pair.
OR put the updated Croc gaiters on sale for Black Friday, and I was able to get a full replacement plus tax and shipping with around $15 left on the store credit.
Excellent customer service and impressive demonstration of standing behind their product and warranty, even for non-original owner.
EDIT: the buckle problem was a known issue with a limited run of the gaiters. The rep I spoke to confirmed conclusively that the issue has been permanently resolved and thus the "updated" tag on the croc gaiters on the web page.
