Sonic Alert Sonic Shaker review

The Sonic Shaker is Sonic Alert's answer for people who travel. Instead of a plug-in clock with a corded pad, it is a compact clock with its own rechargeable battery that you charge over USB-C, and you slip it under the pillow. The SBP200 user guide lists three wake modes (vibration, buzzer or both), a snooze that comes back in about 4 minutes, a test mode and a button that lights the display for 5 seconds. It carries a 1-year limited warranty. That makes it the simplest way on this list to take a vibrating alarm to a hotel, a dorm or a hospital stay. The tradeoffs follow from its size: there is no strobe, the guide describes one alarm rather than two, and a small pillow unit will not shake a bed as hard as a mattress pad on a mains clock. It cost $35 when checked.
