Hey I just asked a question. I just find testimonials that copy and paste a company's marketing material to be odd. :P
If you've read and comprehend the issues raised, they are a) a reaction to the dodgy science they propagate, b) in fact advised people to buy their radiator when the choice is between that and re-cored surplus units, and c) show my disdain for the thugs232's obvious intent to spam.
All of which have more to do with quality of manufactured goods and technical merits.
Why do some dealers/traders for aftermarket radiators sell them with a 1 year warranty when a local manufacturer can't? This of course will be validated across the quality of any manufactured item. This is commonsense, regardless of your level of education.
I'm sure you're more gifted than this.
thugs232, if he had more altruistic intentions he would be extending service instead of spreading commercially inspired "rumors" as his first 3 posts.
