Review on ⏳ Playlearn 6 Inch Sand Timer for Kids – Large Hourglass Timer for Classroom, Teachers, Home, or Office – Durable and Safe - 3 Minute: Enhance Learning and Time Management Skills by Meghan Davis

Purchased for use in poker tournaments, just received. very happy with him - haven't played tournaments with him yet - but hopefully soon. I measured it with a stopwatch and it was very close to 30 seconds - about 31 seconds - not accurate enough by aerospace standards but good enough for board games and the like. I didn't rate durability as I've only had it for a week or two, but it seems quite well made. Probably 4 stars.}The interior is made of glass - beware of children under 7 years.
