Arduino is a marketing company that makes amateurish overpriced dev kits and sells them to amateurs. They have that market largely thanks to marketing moves.

Arduino products rarely sell to people who do any form of QC or comparison shopping - they sell to people who buy the first thing on their mind.

Most of the Chinese embedded companies are engineering groups that understand they are filling the low end of the professional cost-quality curve, but they are still on that curve. For what you pay, they make a great product.
