I was browsing over on www.evolutionM.net earlier today and came across this comparison. It's about "ebay" knock-off brands vs. a reputable brand (Mishimoto to be exact). They even have a couple youtube comparison videos linked to it!

Here's the link:

Anyone else with this type of experience regarding junk knock-off companies with basically zero quality control?

 

A lot of the "knock off" stuff is pretty decent.

 

Yea, well, you may have gotten lucky. QC is non-existent apparently. Look at the pics where the guy compares the straight corner of the wall to the sides of the radiators, the Blackworks radiator is horribly uneven.
