Review on ⏳ EMDMAK Sand Timer Set - Colorful Hourglass Sandglass Timer Pack for Games, Classroom, Home Office - 1 min/3 mins/5 mins/10 mins/15 mins/30 mins Sand Clock Timer (Pack of 6) by Omar Bloomer

Large size, they feel good in hand, easy to read, they like the aesthetics. Super sweet. But very inaccurate, especially over 5 minutes. 30 minutes ended 40 seconds earlier, 15 minutes ended 30 seconds earlier, 20 minutes ended 20 seconds earlier. The smaller numbers weren't so bad. The 3 minute result was pretty accurate, the 1 minute result was 3 seconds late and the 5 minute result was 10 seconds late. I can just tell the kids to finish everything earlier so they have a few seconds to finish the last tiny piece they make. I don't need them to be perfect, but finishing 20-40 seconds early isn't much...
