The clock radio was perfect at the outset. I felt great that we can plug in a USB stick with the desired music and in addition we could use the music from the USB drive as an alarm clock. Unfortunately, I bought 2 and 2 had a limited lifespan: the first "toast" that is, he died and we sensed a burning smell, and the second radio alarm clock clock no longer works. Shelf life 18 months to 2 years maximum. Too bad.
