Summary: Easy if you don't overthink
Comment: I got one of these and I was really pleased. I have Vista and so much is not compatible or difficult, but it worked right away.
I definitely had to read the instructions, but it was pretty easy once I realized that
1. pictures will show as unit is charging
2. you need to have unit plugged into usb port with screen saying "updating" before software on PC to load photos will work.
3. you need to hold down on/off for 3 seconds to turn unit back on if you have turned it off.

Summary: Lame documentation
Comment: After a lot of searching, it needs to be in update mode not charge mode for the software to work.

Summary: Definitely worth it
Comment: I bought this product initially as a gift, and the first couple I bought were great... I think I've purchased 12 total... 3 of the units had some difficulty in holding a charge or turning on...BUT... when I called customer service, they were fantastic, and they sent replacement units that work fabulous. They are perfect for grandparents... etc..I even kept one for myself. Definitely worth the $$$!!!
