Review on 🔒 Master Lock Stainless Steel Barbell Receiver Lock - 5/8 in. Fit (1469DAT) by Nick Cleary

So I bought this lock and used it for a while until I had to take it off and found it was so rusted and rusted that I had to break it to take it off. No problem. I casually wore the rubber boot covering the keyhole and witnessed the user's failure. So I ordered a second one and this time made sure that the protective cover stays on for the entire period of use. Had it on for about 6 months, removed the trunk to open it and the key wouldn't go in. The pens are frozen. I had to spray a penetrating lube and hammer the key in the keyhole to insert it and give the key a hard twist to unlock it. He took it off and a small mound of corrosion fell out of the side hole. Tried oiling everything to see if it would come loose but to no avail. This thing was corroding even after making sure I was using it perfectly, so it's not waterproof or water resistant.
