Ditto, going on 13 years. Use on my Blue Ox tow bar set up.
Buddy of mine just had one of these shear in half, towing a car trailer with his new mustang on it while moving from NC to TN, pulling it with his class 3, he said it was really windy but that the pin was new he had just bought it for the trip. Luckily his wife was following and was on the phone with him when it happened. They got stopped without any damage, safety chains did the job. I recommend the Master Lock series of pin locks, the fit really tight and the key part is at a 90 degree angle, which is why I bought it, my electrical light hook up is in the way for the strait pin lock.
