When I have to download digital pictures on my computer I usually give up and ask someone else to do it. You have to find all the right cables, make sure there all plugged in properly and even then it usually doesn't work. But now I've got a dazzle and it makes taking pictures a lot easier. You take the memory card out of the camera, slot it into the dazzle and then all you have to do is put the dazzle into the usb port in your computer. It's so easy! They do not cost much and it really is worth it if your fed up, like me, of having to sort out all those cables. Dazzle works with most normal memory cards and you can plug it into any computer just as long as it has a usb port.
