Review on ⏳ Secura 7.5-Inch Oversize Visual Countdown Timer for Kitchen - 60 Minute Time Management Tool for Kids, Teachers, and Adults (Blue) by Sasha Hsiao

I changed it from 4 to 3 stars. Initially it was 4 stars because it could only work when the time was 5 minutes or more. It still worked great for classes longer than 5 minutes. Now, after a few months of use, I've noticed that the timer sometimes goes off by more than 10-15 minutes. I can set a 50 minute timer closer to 10:10 but the timer doesn't start until 11:15 (should go closer to 11:00). Not suitable for everyday classroom use.
