Our take on the Sonic Alert Sonic Blast Loud Alarm Clock

The Sonic Alert Sonic Blast is a digital alarm clock built for people who sleep through ordinary alarms. Its 113 dB alarm pairs with a bright flashing light, and volume and tone are adjustable. It also works as a Bluetooth speaker and has a USB port to charge a phone. Against standard bedside clocks it is far louder and adds light-based waking, but it is a corded tabletop unit, not a travel clock, and it has no battery backup listed.
