[sdiy] rare component sourcing: UTSource

[David Ingebretsen]

I've found UTSource to be very honest. In a recent "group" buy of MN3005
chips, the first batch they shipped were fine. The second batch from a
different supplier were fake. UTSource found a different source and replaced
all the fake one which were sent. Their problem is that they are a middle
man. The don't have the wherewithal to test the variety of chips they sell.
They ask their sources to verify them, but, yes they do fall prey to
counterfeits. That said, they have always  made good on the products they
sell.
