... As an ex-boss of mine told me long ago (he was in the construction hardware business) : in China you can buy a $1.25 hammer from any factory. Also, you can request the same factories a $100 bucks hammer to be made specially for your market. But don't complain when your customer comes back to you asking for a refund on the $1.25 hammer's broken handle when it fell accidentaly to the floor. He said: I mean, what did you expect ??? It is a $1.25 hammer for God's sake, NOT a hammer that you can leave to your child as inheritance after you are dead.
... Moral of the story: CHEAP Fingerprint readers = equals to more RMA returns = equals to dissatisfied customers with a blow to your reputation as a serious and professional integrator = equals to welcoming free stress and technical support headaches ....
