Review on ⏳ Runleader Digital 9999 Days Timer: Countdown Tracking and Event Reminder with Backlight Display for Vocations, Retirement, Meetings, Anniversaries, Graduations, Weddings and Premieres (Black) by Angie Jones

I was looking for a timer that can run for 99 hours but I wanted to be able to use it over and over again. For that it works great. I use it to remind me how many days are left until the plant food changes in my hydroponic system so I need it to be over 99 hours. The display is backlit, which I wasn't expecting (a big plus), and it makes an alarm-like sound when the countdown ends. There doesn't seem to be a way to turn this off, but it's not too loud or obnoxious, so it doesn't bother me. All in all a great reusable countdown clock.
