Input:
I'm using this product with my Canon ELPH digital camera. It is really convenient to be able to pop a flash card in and download all the pictures at once. I only have a few nits...For some reason, the drive doesn't work if there are other items plugged into USB ports at the same time. The other thing to keep in mind is that if your camera has a USB connection to begin with, the pictures will download pretty fast, so you don't have to worry that much about battery life (translation: your money may be better spent on higher capacity compact flash cards). Other than that, it's a great product.
