The embroidery work for me now since 4 months more or less smoothly with my SD and SDHC media; now and then there was data corruption that I put on my digital camera. Lately accumulates the number of read errors: Approximately every tenth file my digital camera is "broken" to the PC. Repeating copying works of the transfer, however (mostly).

No question: The unit is conveniently compact and makes less mess on the desk as a reader with cable. But I would say there's a reason why the device is not known, according to the Amazon description as SDHC compatible.
