I bought this MP3 because it was the cheapest one with a name that I'd actually heard of. Whilst it is an okay player, I suspect that it is no better than one of those ones nobody has ever heard of before.

The best thing about it is the internal batter that charges itself via the USB. Three minutes charge gives three hours playback, and you get about 24 hours use from the full battery.

There are two major downsides; firstly you have to use and install Sony's proprietary software, soundstage, and convert everything to the proprietary format before you can upload it. This is so time consuming and laborious that I have only bothered changing the music on it once or twice. The player will convert any other format, but it all has to be processed by soundstage first. On the plus side the compression means you can fit more songs on. It is a 512mb player and holds around 150 songs.
The other problem is the sound-limiting software. It simply doesn't play loud enough and there is no software hack for it.

Other than that it's a pretty mediocre player. The sound quality is average, the features are average; there is a graphic equaliser, randomiser and playlist function, and date and time. You can also change how long the LCD stays lit for. The on-screen menus are pretty annoying; you have to go through a sequence of ten button presses, for instance, to get to your playlists.

Don't bother with this. Either buy a decent player or a no-name one that you can treat as disposable.
