Query: Convenient compact design but lots of problems

I bought two of these - for each of my kids bedrooms. It is nice and compact with the clock and the cd player -- perfect for their bedside music. The problem is they don't keep time correctly -- every time there is a power outage (and they go on the back up battery) both start to run ahead (they seem to pick up 10 minutes every few months). One of them is now not playing the cd without hitting the button five times and turning it on and off a few times. It also sometimes starts playing music in the middle of the night on its own.I was here looking to replace with the Sony (figured it was better quality) and was surprised to see another review liking this one and having problems with the Sony....
