I bought this because I lost the cable that came with my camera and needed a solution NOW. This arrived within 2 days and it's perfect. The Frustration-Free packaging was a nice extra too.
Nice speedy transfers from my SD cards, the 2GB MicroSD card is a bit of a bonus really, I've not used it myself, but I'm sure I'll find a use for it. The MicroSD adapter is very handy, I've used it a couple of times with the MicroSD card from a mobile phone.
The only downside to this is that it's quite wide, so if your USB ports are side by side, like they are on my Mac and most USB hubs, it can end up taking over 2 or 3 ports.
