Easy to use, can fit LOTS of videos and MP3s, and portable. I take it to the gym to watch movies on the elliptical or exercise bike, use it on airplanes, listen to music while I'm taking a walk, etc.There are 3 cons, however, which is why I give it 4 stars as opposed to 4:1) The fact that it's a custom USB cord instead of a standard one. I'm scatterbrained and I misplace it a lot when I charge it on my laptop. While I have tons of regular USB cords lying around, it would cost me $20 to get a back-up of this custom one. Annoying!2) The volume control doesn't get as loud as I'd like.3) Battery life is somewhat short.That said, I'd recommend this product. It's fun having portable video access, and it makes working out at the gym go by A LOT faster :-)
