I must say first off that I got this as an ex-display from my local Sainsbury's for £10, thus the good value rating!
Sound quality seems pretty good, storage for the price is good, controls fairly easy to use (my 7 yr old can use it!). The only snag is that you have to install sonicstage software (if you drag & drop files without it you can't then play them through the player despite them playing off the player through a computer - if that makes sense!). It's really annoying!
However, if you can get one for £10 it's a bargain!
