A few months back I bought a new alarm clock because my old one died.
This one is whiz-bang with features. Even sets itself to the atomic clock automatically. I don't even have to worry about daylight savings time. Yay.
It's got a "nap" feature. If you press the "nap" button, it goes into nap mode. So after a specified amount of time, from 10 minutes to 2 hours, the alarm will go off. Pretty handy! Two problems. That nap button is right near the set-alarm button. There's no way to turn it off. Or at least not that I've found. Way too frequenlty I reach over to set my alarm for the next morning and accidently press that. My only recourse is to set it to it's minimum time (10 minutes), wait for the alarm, and turn the alarm off. Several times now I've spent the entire 10 minutes trying to figure out how to turn it off.
My new plan is to remove that button.
Edit: Update -
I did it again. This time I unplugged the damn thing instead of waiting for it. I found out 20 minutes later that it's got a battery backup for the alarm! /sigh
