Have the Transcend PF830B in use. Good image quality, service ok. All pictures easily be as big problem I see the folder navigation. I have my photos copied to the internal memory. These are sorted into subfolders, so you can distinguish between the various galleries. While I can jump in the thumbnail selection in a folder into it, and select images. But I do not come back to the parent folder. After selecting the folder icon back the message "Error in file format." But in the slideshow or single picture view I can look at all the pictures without problems.
Have all been tried with empty folders, with different resolutions, photos from different cameras, even with the demo pictures on the internal memory, with different SD and SDHC cards of 2GB to 32GB memory.
Images were transferred to the spokesman cards each from a Win7-breaker.
