I bought a locking pin like 15 years ago. that one still works good but has no dust cover and need to WD40 to get it off sometimes. This one I put on my wife's car. It installs easy but does not feel ad hood as the the other one I have.

Generally OK product. Not very weatherproof. Not very rustproof for long use. Keylock not exactly bank-vault quality, but OK for anyone who does not have a bobby pin! Good product for the money if you are willing to keep it well greased against corrosion.
