Colorful Sand Timer, Hourglass Sand Clock Timer Set, 10Sec 15Sec 30Sec 1Min 2Min 3Min 5Min 10Min for Kids Brushing Teeth, Classroom Home (8 Pack (8 Colors))

This set includes 8 colorful sand timers, each top is labeled with the time. I tested each one and recorded their actual run times below: Color Labeled Time Actual Time Blue 10 seconds 7.79 seconds Black 15 seconds 15.23 seconds Red 30 seconds 30.50 seconds Yellow 1 minute 1:05 minutes Pink 2 minutes 2:00 minutes Orange 3 minutes 3:11 minutes Green 5 minutes 4:47 minutes Purple 10 minutes 9:42 minutes The colors are vibrant and fun, but the tops and bottoms of the timers are not glued on straight, which makes them look a little off. You can see in the picture how they don't quite stand up straight. However, each timer still sets upright and functions properly despite that flaw. I originally purchased these for my daughter to use while brushing her teeth, but we’ve found them really useful in our homeschool lessons too—especially for timed educational games. They’d work great in a classroom setting or for board games at home. That said, I don’t really see much use for the 10, 15, or 30-second timers. It would have been more practical to have a 15-minute and 20-minute timer included instead. Still, for the price, this set is very affordable and we’ve already used several of them for a variety of purposes. I give this 4 stars due to the crooked lids that cannot be adjusted and the 3 extra second timers that I see no use for, however I would definitely recommend them for anyone needing a time for board games or educational purposes.

These are fun timers, and most of them are accurate, give or take a few seconds. But I tested the 10 minute timer three times and it was off by a couple minutes each time. Hopefully I just got a faulty one. For our purposes though, these work great. I think they're very cute, and my kids are using them for various activities already. I love the colors, and the quality is decent(minus the faulty 10minute timer).
