Review on Syrox Black Mini Micro SD Card Reader - Fast and Convenient Data Transfer, Portable and Plug-and-Play Friendly by Johnny Wheat

I like that it's so small and unobtrusive. And it works. Something like. I bought a few and they are in a USB hub with the chips installed. About once a day they all become unresponsive and I get an error for each one saying they should be extracted before uninstalling, even though they are installed and enabled. I'm using a MAC and it might have something to do with it, but I doubt it. It's also worth noting that they all descend at the same time. Maybe something in the hub. Who knows. Also, I love them, but as another reviewer said, it's very easy to lose sight of this little gem. Be careful.
