SuLiao Hourglass Sand Timer for Kids: Large Acrylic Unbreakable Sand Clock 2/3/5/10/20/30 Minutes, Plastic Sand Watch, Colorful Hour Glass Sandglass for Classroom Games Kitchen (Pack of 6)

These are fun and colourful and my kids loved using them to help them time various tasks. For example, we use them for homework, meal time and going poo (my son used to take forever on the toilet just playing). They're plastic so I don't have to worry about them breaking on the floor. The build quality is not bad. As for accuracy, they're really not the most accurate. Our 3 min timer runs about 2:04, 5 min timer is 5:29, 10 min timer is about 9:31, 20 min timer is about 21:18 and 30 min timer is 30:37.

Perfect in classroom to track time for various tasks

Given the disclaimer of it being 10% give or take on the time, they’re pretty accurate. Super easy to hold, even for little ones. He’s dropped them a few times & they’ve held up well. Bright colors are definitely a win. Kiddo loves the pink 30 min.

Nice , great product

I like these timers. They help my children take turns/share in the classroom.
