The Transcend Card Reader immediately improved the way I work with photos. I use a CompactFlash card and need to move photos across to a MacBook for editing, multiple times a day. The reader is compatible with CF (Compact Flash), microSD and SDHC/SDXC cards and has fast USB 3.0 data transfer speeds. Also backwards compatible, so works with USB 2.0.The reader has a clean stylish design with a subtle blue LED which lights when connected to USB 3.0 such as a Mac, PC or USB hub. It flashes when connected and when in use such as transferring photos, media files or documents. Comes with robust 45 cm USB 3.0 lead.Highly Recommended!
