Review on ⏲️ Red BALDR Kitchen Timer for Precise Timing by Tina Jones

I bought this timer as a visual aid to help students who are having trouble working on assignments and sitting in a group. The timer helps students see how much time it takes them to complete an assignment. We worked together to set goals and as soon as the students were able to reach the end of the preliminary goal, they were rewarded. This timer really helped them because they can easily see the remaining time thanks to the red mark on the timer. It's magnetic, which is very useful. The only downside is that it doesn't always ring. It only rings 50% of the time. I wonder if the one I have is defective? If the timer made a sound every time, that would be perfect.
