Review on ⏱️ Small Timers for Classroom Teachers and Kids - 6 Pack Digital Kitchen Timer with Magnetic Back, Stand, ON/Off Switch - Blue and White by Angela Fields

They look nice and work well, but the problem is that they stay on when you turn them on, instead of turning off after say 5 minutes of inactivity (like other timers). What I have). I can't imagine the batteries lasting very long with the timers on all the time (it's unrealistic to turn them on and off that much throughout the day). Also, they don't come with batteries. I think you get what you pay for.
