Respect ... the thing is small and can what. The SanDisk 'Extreme Pro' microSDHC UHS-I (manufacturer's specification: 95 MB / s) mastered the reader with full speed. In benchmark he cut even slightly better than the flagship "SDDR-289" from SanDisk (see above review). However, at 95 MB / s on the bus final conclusion that is, if SanDisk someday should invent 200 MB / s card, would have her a new reader. In addition, not both card slots can be used simultaneously, that is either mSD _oder_ SD card. For "consumed" the reader, however, only a single drive letter.
Ultimately, every reader "his" preference for certain cards. Anyone with the above limitations has no problem should definitely give this thing a chance. Even a firmware update tool is available (however the delivered firmware was currently in test).
