Query: Extremely disappointed

I've owned this for about 3 years and I'm shocked at how badly it has performed.First, the good. The quality is good for what you pay for.Now, the rest. It can't keep time. The clock loses about 10 minutes every 2-3 months and has to be reprogrammed. Can't believe that's an issue in this day and age. Second, the speakers now thump wildly if it is left plugged in. I googled the problem and it seems to occur with car speakers but I don't know how it can be fixed for less than the cost of replacement. The interface is annoying - buttons in strange places and not very responsive. The remote died after two years.I don't understand why this received such a good review on Amazon.
