PROS / You can customize the alarm by changing the volume, tone or having it vibrate to wake you up.
CONS / The unit doesn’t alarm when it is operating on battery.
VERDICT / While this alarm clock lacks several features, such as a temperature and date display or music player, its sound and vibrating alarms are a great option for deep sleepers.
The Sonic Alert’s Sonic Bomb with Super Shaker alarm clock wakes up even the deepest sleepers in the morning. While it does lack several features, the combination of a blaringly loud alarm and vibrating extension that shakes your bed gets you up in the morning.
This alarm clock proved to be accurate in all of our tests. Not only did it go off at the time we set it to, but it also snoozed for the exact amount of time the manufacturer listed. The alarm clock allows you to keep snoozing your alarm indefinitely and does not reset for the next day until you turn the alarm off. This digital alarm clock has an adjustable snooze interval you can set anywhere between one and 29 minutes. However, the default snooze setting is set for seven minutes.
This large display alarm clock runs on AC power; however, it has a 9-volt battery that keeps the time and alarm settings during a power outage. While the battery maintains the time, the unit does not alarm on battery power. The alarm clock displays the time in large numbers, and you can adjust the brightness if it is disruptive to your sleep.
The battery alarm clock does not have a radio or very many features. You have to set the time and daylight saving time manually. Since the alarm lacks a weekend mode, you need to turn off the unit on the days you don’t want to wake up early. It’s also missing additional features like a date and temperature display.
This alarm clock has dual alarms, so you can set it to go off twice each morning, and you can choose between beeping, vibrating or both. Rather than progressively waking you, this alarm starts off loud with flashing lights and vibrations, but you can adjust the tone and volume.
Sonic Alert offers a one-year warranty for the Sonic Bomb. You can contact the company by phone and email for customer support. We found that email response times varied.
The Sonic Alert’s Sonic Bomb with Super Shaker doesn’t have as many features as some of our top-rated alarm clocks. However, between the loud alarm, flashing lights and vibrating extension, it is sure to wake you up. Still, you can adjust the intensity of the clock’s tone and volume to fit your preference. This alarm clock is best if you are a deep sleeper or have trouble waking up in the morning.
