Having had the player for a few months I have nothing bad to say about it except a few glitches here and there which can be easily fixed through firmware update. When scrolling through the song list there is a noticable pause when album art is being loaded (not a big problem, pause may only be 200 ms). Another thing I noticed which was annoying more than anything else was once you connect the USB cable and have headphones plugged in at the same time unclipping the USB cable without removing headphones is very difficult unless u have long nails. There seems to be no support for x64 operating systems when running Sansa Updater (workaround = right click > run as WinXP).
Apart from these little things the player is very good and for the 50 quid I paid for my 8 gig player is much better than spending over a 100 for some of the competitors with same sized players. I already had a spare 8 SDHC card and it plugs in very easily and neatly and now I have 16 gigs of space to work with. FLACs work great and although pictures need to be resized before viewing on the player they all work fine in jpeg format. Sound quality as mentioned in the review is very good. Radio recording and voice recording works great and sound quality is as good as you hearing it live. I have no complaints about the functioning of the player.
My advice get some decent in-ear headphones (I got creative ones for a 10er) and enjoy what this player has to offer.
