Sonic Alert
Sonic Alert Sonic Bomb Dual Alarm Clock with Bed Shaker (Black)
Pros
- Three wake channels at once: a loud adjustable alarm, flashing red lights and a bed shaker
- Choose vibration only, sound only, or both, so a partner isn't always woken
- Adjustable alarm duration (1 to 59 minutes) and snooze length (1 to 30 minutes)
Cons
- Plain, dated design with bright red digits that some find intrusive at night
- Very loud at full volume, which can wake the whole household
