Query: Good concept with a few hassles

I really liked the clock when I brought it home. The features are great, the alarms are easy to set, the display is easy to read. I've had some problems with it though that has me looking for a replacement:--The biggest problem is the sound of static coming from it all night. The radio is off, and I can't quite figure out if the sound is coming from the speakers or the circuit board. Maybe this is the sound it makes before the LED fails?--The display is too bright even at the dimmest setting. I think they tested in the lab by turning the lights off, but never left time for their eyes to adjust to the dark.--Sometimes I wake up thinking it's 9:05 in the morning only to realize the unit is displaying a radio station of 90.5, though the radio is off.The nap feature is nice, and the button placement is great. I don't know if my problems are due to unit-to-unit variation or design flaws.
