Yousheng Classroom Game Sand Clock Timer Hourglass Sandglass

I ordered the hourglasses to be able to show my children smaller times and thus promote their self-efficacy. For example, when brushing your teeth, but also when studying, consuming media, cleaning up, etc. So I can say "x more minutes" and you can turn the clock independently. That works really well. Seconds don't matter to us. Therefore: great value for money and recommended. :)

My child LOVES them!! Timing may not be as exact, but it gives him the right odea of how ling things take. Also, they are safe to use for kids as the glass is in a plastic cover - unfortunately, he broke one by dropping it high from the sofa to the hardwood floor, but everything was contained inside. Great purchase.

I ordered 2 times. When brushing my teeth I gave my granddaughters the yellow 3min. Yesterday I told them 10min and so I put the red one up. It was not discussed. I tested 2 and they are accurate

Good quality and it arrived earlier than expected, since I put them into operation, the one that lasts 2 minutes stops, it has some sand with a defect which does not allow it to graze and it has to be hit to get it stuck.
