6 Pcs Hourglass Sand Timer Set 30 Sec 1 2 3 5 10 Min 8.8 cm

It is so useful product

Good for kids

This is a very good set to introduce sand timers to kids and introduce them to the concept of duration, fast and slow. It has good packaging and is easy to play with.

Not accurate. The 5 min timer has no space for the sand to go so it doesn't work. Low quality

PRODUCT IS VERY GOOD AND VERY HELPFULL IN MY TRAINING OF AUTISTIC CHILD. TIME AND COLOUR CONCEPT IS EASY UNDERSTOOD BY THIS PRODUCT.

Awesome quality of sandclocks, came in a day, packed well.

Out of 6 timers, only 3 timers are accurate. The 30s, 1min, 10min are very close to the expected time. 2min, 3min, 5min are way off by at least 30 sec. Further more, the time depends on direction. For example, the 2M timer takes 2min 25 sec on one side, 2min 40 sec on the other side. The sand is completely sealed inside glass. There is no way to modify it as well.

This is so useful. It is very important to take brakes when you are studying. Since there are 5 different timers, you could study for 10 minutes and take a break for 2 minutes. And then you could study again for 10 minutes and then take a walk for 5 minutes. You also have a timer for 30 seconds so incase you need to make a call you can use that
