Monsin Sand Timer, Hourglass Sand Timers Colorful 1 Minutes Sandglass Timer with Protective Cover for Classroom Home Office Cooking

I really like this 5-minute timer the way it's made and the vibrant blue sand. Sadly though, it's missing 7 or 8 seconds worth of sand (I ran an electronic timer against it to check its accuracy). That is the reason for 4 stars and not 5. Not the seller's fault, but the manufacturer clearly didn't measure the amount of sand required for an accurate 5 minute's duration. It's not hard! 🤷‍♂️ 1 or 2 seconds ok, but not 8.

I used these in my 4th grade classroom this year for students that struggled with spending too much time on a question and they worked beautifully. The students would grab them when they started the assignment. When the started the first question, they would start the timer. Their goal was to be finished with the question before the timer ran out. When they started the next question they flipped it again. I think they would also work for students that go too fast. They are easy to read and not expensive. I kept them in a bin with some fidget toys for assessments and the students that needed them would grab them. I’m not sure how accurate they are but they helped my student that struggled with time management. She didn’t need to use it on every question, just ones she was stuck on so she had a visual reminder to not spend too much time on a question she was unsure about.

We needed to put my husband on a timer when playing games. This is perfect. Good quality. Works as expected. Seems pretty durable...not worried about it breaking if falls over on table or carpet.

simple product, does what it has to do...

First of all, I didn't expect this to be dead on 30 minutes. I did expect some deviance in time measurement. But to be 91 seconds off is a little much. I use this for instrument practice for my children. They get out early because of this. Is it a big deal? No. But don't use this in anything that requires decent time measurement.
