Double USB
Double USB

The chance of plugging in the USB up side down is 50% because USBs and USB holes are small. Double USB has reading area on the both sides of it which helps users to stick USB into hole more easily and correctly. When you always put your USB in to the right hole it can also prevent damaging reading area and getting scratch.

With the Double USB user can put into the right hole 100%!
