Zoolase Retro Double Bell Alarm Clock vs Sonic Alert Sonic Bomb Alarm Clock

Buy the Sonic Bomb if you truly sleep through alarms or are hard of hearing. Its 113 dB alarm, flashing red lights and 12-volt bed shaker under the pillow are a multi-sensory wake-up that a bell clock can't match. Buy the Zoolase twin-bell if you want a quiet retro metal clock with a loud ring, silent movement and no cord. The Sonic Bomb is the stronger alarm; the Zoolase is the nicer object on a nightstand.

• Choose the Zoolase twin-bell clock if you want a classic metal analog clock with a loud bell ring, silent ticking, luminous hands and a night light, and you don't need a shaker or flashing lights.
• Choose the Sonic Bomb if you sleep through normal alarms, have hearing loss, or share a bed with someone who does, and you want adjustable volume, a vibrating bed shaker and flashing lights.
