I agree, if a vendor makes a poor product then by all means let people know. I have heard many people say they love Wisco pistons and I have heard people hate them, and maybe they hate them because of a motorcycle issue or some other reason, I am sure there are plenty out there that have no clue as to which are better or why. I just think you need to start your own thread and publish your findings good or bad. Now if the said vendor in your thread wants to defend himself fine but I think a vendor who is a stand up guy will make things right before it comes to this. If not by all means let people know you where not happy and maybe someone or that vendor can be some help to make it right.
