Review on All-in-1 Universal SmartMedia Card Reader Writer: Efficient USB Multi Card Adapter for Windows, Mac, Linux – Slim Hub Reads Smart Media, xD, SD, SDHC, SDXC, UHS-I, MMC, MS Pro Duo, CF, MD, Camera Flash Memory Cards by Neil Biondo

Compact design works well. Some of the slots can work with two types of cards. It's a very light plastic and not very strong. In fact, the thin divider between the two right slots was already broken when I received it. I have chosen not to bother with the return/exchange as once the broken divider has been adjusted it does not affect the function. I have a music device with a Smart Media (SM) slot, so I wanted a device to move files between my computer and this device. That serves the purpose well. A NOTICE. If you are a Mac user and want to use an SM card reader with a Kurzweil keyboard, I recommend a software utility called Blue Harvest that will help you remove the many invisible files that Mac OS adds. on external cards that are installed. It's very useful.
