The problem with stuff like this is that the buyer often leaves feedback after receipt and is satisfied with the transaction. Weeks or months later after they install the parts and find out they were crap it is too late to revise their feedback. The numbers don't really tell you much in that regard.

 

the numbers simply tell you how well the seller is going to complete your transaction such as fast shipping, all parts in the kit as explained (whether there the right parts or not and if they suck). Miami is right, the part could go out after 2 weeks for every single one of the people that bought these from him but we will never know.
