Review on Efficient Micro USB to Mini USB 2.0 Adapter: Streamlined Connectivity Solution by Keith Montague

This is a handy adapter. However, there is no indicator at either end of which side is up. Mini-USB is obvious, but Micro-USB is very small and difficult to identify, making comparison difficult. I found that they are rotated 180 degrees; up to mini-USB versus up to micro-USB. An indicator would be useful as using such a small connector could damage it.
