Review on Efficient Fitness Timer Stopwatch: LED Digital ⏱️ Countdown Wall Clock for Gym (1.5inch Digital High) by April Masters

This timer is a great value. I installed it in a church so the warden could keep track of how long he was speaking. The display is bright and clear, shows the exact time. One thing it doesn't mention is that it shows the time even if you unplug it! At least for 24 hours. The display part doesn't need batteries, it needs to use the super cap to keep time. You can turn off the display with the remote control when you want it to be dark and it will show the time when it turns back on. Similar timers cost $700 and up.
