Review on ⏳ Wood Hourglass Sand Timer – 8", White Sand, Black Frame, 60±6 Minutes, 8x4x4 Inch by Tammy Miller

When I first opened it, the sand got stuck in a few minutes and it wouldn't come off. I tried shaking and flipping it multiple times in a few days and forgot about it for a week. Then when I tried again, everything worked. Since then it works. We use it to control TV time for preschool granddaughters, they know their time is up when there is no sand. When my kids were little I used one to sleep in - you had to lie on the bed until all the sand crumbled. Of course, they always fell asleep anyway, but it gave them a sense of control when they thought they didn't need sleep.
