Query: Works perfect!

We purchased this as a gift for my wife' grandmother & it works great. The sound is clear, it plays CD-R & CD-RW, and its very easy to use (her 76 year old grandmother can use it). It also has a sleep timer that can be set @ 90, 60, 30 & 15 minute intervals. It could be improved with the addition of a battery back-up (or better yet auto set clock) but that is the only problem I see with this unit. Highly recommended for putting yourself to sleep with music!
