Brands

I personally think its very difficult to determine if a part is "quality" based on the brand. There is constant changes is supply chain, company, etc, that there is no way to keep track. The online discussions focus on someone who hates a brand from 1 bad case or simply because they are racist against the company's origin country...

Some good metrics are:

• Age of company
• Size of company
• Supplier to OEMs
