This case is surprisingly useful. It allows me to keep all my memory cards and extra batteries in one place. The battery slots have little indicators to help remind yourself which one is charged and which isn鈥檛 - a nice quality-of-life addition.
The only negative I can mention is that it鈥檚 HEAVY. Once you load it up, it鈥檚 probably about a pound or two. Not the end of the world, but it does prevent me from clipping it to my camera bag on a whim; it鈥檚 more of a backpack stow.
