So far a great set of cleats that take no obvious damage by simply tightening them down like regular cleats do. It's also nice that it will be harder for thieves to steal my wheels as they are unlikely to have any of these keys in their theft inventory. A good way to protect your wheels is to buy two or three sets of them with different key profiles and separate them in cleats on your car. It costs more, but at least 2-3 layers of protection instead of one.
