The Amkette Multi Format Card Reader is compact, convenient, and is great to have around if you own memory cards of different types. With a small blue light to indicate that it is powered on, it supports Memory Stick (MS), Memory Stick Pro Duo, SD, MMR, RS MMC, M2, TF and Micro SD memory formats. If you are the type of person who likes direct access to your memory card (not having to connect your entire device and then selecting mass storage), and want a faster alternative to upload music and other files onto your phone or other device, this is the product for you. The only complaint I might have is that the build quality is slightly compromised at the area where the USB wire connects to the body (which is a liability only is used roughly).
