Review on Gorilla Automotive 71623NBC 'The System' Acorn Black Chrome Wheel Locks: Ultimate Security for 5 Lug Wheels (12mm x 1.25 Thread Size) by Samuel Hansen

Excellent quality, easy installation, very durable. They fit my wheels perfectly. I tried to remove them without a key, didn't succumb. They're worth protecting your drives, especially ones that cost a lot of money. It also comes with a product number to get a new key from the company for a fee if you lose it, but even that isn't too expensive.
