This model is probably already starting to show it's age. It's a simple device that I first bought to use in the car but I've found increasingly useful recently as less and less things actually take a CD. It could probably be found for a song now.
When empty is weights next to nothing, being only a plastic shell. It's about the size of 2 CD cases in thickness and only a smidgen bigger than the disks themselves. There is no unnecessary stuff on this model, and it shows it. It's standard, from the opening catch to the two double A batteries. The rather boring exterior, 9 buttons and little led screen, hiding a rather boring interior. The batteries cover is inside, under where the CD sits, which is a nice touch, to keep you from pulling it mid song.
It's simplicity means that it doesn't scratch up, it doesn't break easily or start to look old after it's been bounced about a bit. I'd be hard pressed to find a way of breaking it to be honest. It doesn't have any sort of attachment device which is a downside, for some.
It does rattle a little when traveling but the CD and the sound seems unaffected. It's got a good sound through standard headphones, packing as good a punch as one may expect. It's a nice clear sound and it doesn't jump at all. I've used it as a portable sound system on camping trips and it's always done fine. It's happy to play MP3 CD's as it's fast to publicise. I find that it processes them a touch slower and so the initial start delay is noticeable.
If you want something compact then it's fine. If you want the latest gadget then you are way behind on this one!
