I purchased a clock radio [Model ICF-C1PJ]. After a couple of months or so, it stopped responding to button commands and starting having a mind of its own mind. It would come on by itself and none of the buttons work. The alarm would go off at random times. I unplugged it, only to find it continuing with the battery backup powering it. It was useless.
Shame on me, I assumed this unit was a lemon and I purchased another one for over $60. Within 2 weeks, this unit starting doing the same. Since that time, I've discovered this is a common occurrence and detailed across the Internet.
I've reached out to customer support with no luck.
