As a result of my tests, I determined that these replacement bolts were cheaply made and failed to hold up under normal driving conditions. The only pro is that they were cheap, but that came at a cost since they ended up causing damage to my vehicle. The con is that they don't perform their intended function and can lead to dangerous driving situations. Don't waste your money on these subpar tire bolts.
Pros
Easy to install and fits perfectly in the Mercedes
Cons
Compatible only with Mercedes models, limiting its usage
So far so good, just put them on. Only time will tell how long the coating lasts and how durable they are. I've worn a set and no chips or anything so time will tell but I can't rate it a 5 yet until a few months and a few washes and we'll see how the finish turns out.
They appear to be painted and have a relatively smooth finish. The website says they're made from similar or equal strength nuts to the OEM, so I'm giving them a 4 because they weren't that cheap for regular cleats. Hope the quality lasts but we'll see if they look decent on my rims so I'm giving them 4 stars for now. If the paint peels off, I will remove it accordingly.
