Review on Circuit Performance Chrome Closed Security by Peter Burkart

These "security locks" are a joke. Save yourself some money and skip these flimsy, unreliable locks that barely provide any level of security. The only pro is that they have a shiny chrome finish that makes your wheels look a little nicer. But the cons are definitely more significant: they are not durable or reliable, they are easily defeated by thieves, and they give you a false sense of security. Don't waste your time with this useless automotive product.
