My ebay ones prolly low quality compared to Amazon ones with reviews. I was just sorting through my micro-usb cables and some would not work. Low quality stainless and got rusty//// When I have time I will file off the rust to see it this fixes them
Not all stainless steel is rust proof...low grade is not.
EXAMPLE: I have been buying ebay/chicom rechargeable AA batteries for fun. I am about to buy some at Amazon (part of my 35$+ order w free shipping) that are verified...as in lots of good reviews. Tenergy batteries.
No quibbles with my 59C USB cable.
