I've posted my experience with 440Source here before.

Despite me having their heads, water pump, housing, pulley, etc., having great success with their parts and even defending them regularly, I had one of their balancers come apart. After ignoring my e-mails, I posted about it on here and they played the blame game. Former employee got the e-mail, blah, blah. I'm done with them as well.

You'd think that someone that has their parts on a car that torture tests them like I do and is willing to give them positive feedback would be treated a little better.

F 440Source.
