Review on Hourglass Sand Timer - 5/10/15/30/45/60 minutes Sand Glass Timer for Various Occasions - Perfect Mantel, Office, Desk, or Shelf Decor - Ideal Christmas Birthday Gift - Fun Games, Classroom Timer, Kitchen Aid - (Blue, 5 min) by Trian Wright

Edit: The seller sent me a replacement and it works great! The hourglass wasn't a necessity, especially in the age of cell phones. We all have a timer at our fingertips. But having an old-school hourglass makes things so much more fun. Just being able to watch how slowly time goes by. We use it to play with children, to clean or to watch TV. They are fun to play with and fun for kids. This hourglass is made of durable material but may break due to the inner glass. The time is also very accurate!
