SHARP Twin Bell Quartz Analog Alarm Clock, Black, Loud Alarm, Battery Operated

Amazing. I accidentally ordered this, thinking it was a WIND UP clock. No batteries. BUT it has been almost a month since I revived it. The clock is keeping time perfectly. AND the alarm setting is used several times a week (as backup to my cellphone when weather is incoming)…. ON THE SAME DOUBLE AA BATTERY! Fantastic purchase.

Finally, a solution for moms of teenage kids everywhere! My son absolutely hates this alarm — which means it works perfectly! He's an incredibly heavy sleeper and almost never wakes up on his own, but this clock changed everything. We've tried it all: fancy alarms with sunrise lights, ones that play music, even those that shake the mattress — nothing worked. But this simple, old-school design did the trick. It's loud enough to wake the whole house if he dares to hit snooze. A true lifesaver for parents of deep sleepers!
