Pros Nice and compact and allows you to play any mp3 player with a standard headphone jack. The sound is decent. Can play music from an mp3 player or computer. Given that there aren't many choices for those non-iPod users, this was a good find.
Cons The "cradle" only designed for the small e250, so anything larger won't sit on the cradle, making it useless.
Dock doesn't charge the mp3 player.
USB for attaching to computer doesn't provide power, so you have to plug in the dock or use batteries.
Summary I really like this unit. It's portable and a nice sleek design. The sound is half decent for a unit so small. I wish the cradle for holding the mp3 player was more adaptable so that players larger than the tiny e250 would sit smartly on the unit instead of dangling off to the side. The unit comes with a number of good accessories, so you don't really need much more. I highly recommend this unit for all you non-iPod users out there.
