Sharp LED Digital Alarm Clock, Swivel Base, Silver Case, Red Display, SPC033D

Large, bright display is easy to see across the bedroom. It plugs into normal outlets with 60 cycle AC current, so that the clock can use the 60 per second changes to keep perfect time over any day, week, month or year. If your electrical power blinks or is off for several hours, this clock will use its internal clock circuits to keep the time, if you have installed an optional 9-volt battery in the bottom of the case. The battery will last its shelf life, since it is not used when the AC power is on. This is a full function clock AM-PM aware clock, and is easily settable with its 3 buttons. I opened the box, put in a fresh 9-volt battery, plugged it in, set the time to 7PM, and have not touched it since that day. It always displays the time that matches my computer and my phone. I have had several power interruptions, often just a few seconds, and the clock is not affected at all. Light intensity and alarm volume is settable, however, I just use it for time. Even the smallest clocks plugged into AC outlets have alway been very accurate, and so is this one. Very reasonable price for an LED display clock that will likely last decades.

The numbers are larger, easy to see and the illumination is bright. I like that I can swivel the screen a little at night so that it does not interfere with my ability to fall asleep.
