This is only $14 dollars but seriously, don't waste your money! Despite saying in the description that it works with windows XP, it doesn't. So don't even bother reading on if you only have windows xp (or mac).
Basically this is a keychain with a small screen, 1.5 inches, that scrolls through your photos you can have up to 60 photos held on the device but you can always change them around. I have to admit, it does look quite cute and it even comes in four different colors: red, blue, white, black. However the picture quality is just "ok". I think that they have come up with a good concept but in reality it just isn't practical. I mean how many times are you going to get it out of your pocket and just stare at photos on a tiny little screen.
To sum up why you shouldn't buy this has to be the battery life, in my experiance it only lasts about 3 hours.
