This kind of thing annoys me too:

FOUR different types of engine mounts. Price isn't an indicator anymore, and 'genuine' Volvo doesn't mean a lot in recent years either. So I have no idea which ones are rubbish (or maybe they all are).
e.g. Meyle used to be a brand to be avoided. One is Taiwan. Another is India. That leaves Volvo. But it could just be one of the other 3 relabeled.
FCP just say, "We guarantee all parts - just return them." Useless to us in Australia. But I've also seen them say on a forum something like: "We have to make a choice - to provide a cheaper part with a shorter life, or provide nothing." (Well how about demanding a better product in the first place if that manufacturer wants you to sell any of their parts.)
