Review on ⏳ Mifuner 5-60 Minutes Mechanical Countdown Timer: No Battery, Three Colored Visual Disk Timer for Teaching, Cooking, Working, Exercising - Foldable Legs & Hanging Hole by Alexandra Marie

The timer is versatile as you can attach it to a magnetic surface with a magnet or simply use it on a stand. The red, yellow and green visuals are very useful. If you only see red it means less than 3 minutes left, yellow shows 8 to 3 minutes and green means more than 8 minutes. This makes it very easy for students to quickly see how much time they have left. The alarm clock sound is loud enough to be heard in a large classroom. For kids who can't recognize numbers, this is a great visual time tracker. All in all, this is a great visual timer to use in the classroom.
