Average speeds (definitely not USB 3.x), no support for two cards simultaneously, lasted for two years until the microUSB connector (located inside the USB port) decided to open up as I was removing it from the computer's USB port, get stuck there and require me to break it to detach and remove it (I had barely used the microUSB twice until then).

Luckily, the computer port is intact, but we don't play with these things. Two stars instead of one because I reserve judgment for my own mistake, but if I wanted a USB 2.0 reader, I would definitely buy one of the cheaper identical ones in the category.

I expected much more!! It works like a usb 2.0 (speeds). I think that's where the conversation ends. Just under 1 minute for 1gb. I expected less than 20 seconds.
