Rating: - Own one, pretty nice
I'm not sure why people think it deserves a 1 star rating just because they don't have Vista yet. Not really fair if you ask me. The product itself I am a fan of works great. Battery life is better then most.

Rating: - A piece of junk
It is supposed to work on Macs running OS X but the software crashes when you click the popup box that tells you to make sure it is plugged in. Called customer service and they told me to restart my computer and reinstall the software, then restart it again. Still didn't work. Tried it on two other Macs running slightly different versions of OS X still didn't work. This was purchased at a Big Lots store so that should have been a clue that Coby is dumping their defective product.

Rating: - One Works, One Doesn't
My daughter sent two of them for my husband's and my birthdays. I finally got around to setting mine up this weekend. It took a while to get it to work but I finally downloaded 43 pictures of my grandson, hoping to be able to add on another 17 in a month or so. I then tried to download the same pictures to my husband's keychain but my computer keeps telling me that there is no program installed. I uninstalled it and reinstalled it to no avail. I fooled around with it for about an hour and gave up. I tried again last night, but gave up out of frustration. I am going to dump it. I do not recommend buying this keychain. It is definitely not worth the aggravation.

Rating: - does not work on my mac os x computer
I do not agree with even the one star, I would not give it a star at all. This product was purchased because it was stated that it worked with my mac os x computer. It does not. I was told by multiple tech supporters that some times it does and some times it does not. My advise is don't take a chance.

Rating: - great for free
I got 2 of these for free with Pepsi points. I would probably be disappointed in the quality had I paid $20 for this.
