I needed a key for two of my cars. Unfortunately, this wrench doesn't fit every car for two reasons: First, it's definitely an SAE (American Standard) set, not a metric one. I needed 21mm and 13/16 was barely small. Second, the wrench is too thick to use on aftermarket tires. Overall build quality seemed a bit cheap but acceptable. Take it for what it's worth as I haven't strained the tool to check the quality. Not compatible with: Stock 2006 Toyota Matrix rim and ICW Racing Taboo lug nut.
