The RCA Lyra is cute and compact. It also sounds good. Unlike those multi-functions buttons on other models, the Lyra has separate buttons for Stop/Play/Forward/Backward; so they are easy to operate. As it's been mentioned in many of the reviews before, the battery door feels quite flimsy. I worry that it may break off each time I changed the battery. Battery life is very good using NiMH rechargeable.One important point: It's great that this player accepts SD card for extra memory, but there is an undocumented limitation: I'm referring to the 128MB model. While the player can read from a 1GB SD card, however, a maximum of 184 songs can be recognized. The PC sees the SD card as an additional drive and you can stuff the 1GB card full with songs, but only the first 184 can be played! Say your typical song is 3-4MB a piece, then effectively, any extra memory above 512MB is not usable. That's a shame.
