Review on ⏳ PROLOSO 30 Sec Sand Timer Hourglass Sandglass Clock Countdown Bulk Toy Set - Fun Timers for Kids Games, Classroom, School - Party Favors Pack of 20 (White Sand) by Elizabeth Morrison

Upon receipt, still in the transparent bag they came in, I turned the whole bag over so all the white sand started flowing at once. I timed the test by setting the watch's timer to 30 seconds and found that each hourglass completed its task in 30 seconds ± 2 seconds, which is amazing considering the price. I use them primarily at hand washing points around the house (4 total) and for distribution and backup storage. The fact that they are designed to wash hands for 30 seconds instead of the recommended 20 seconds is actually an advantage as there are 10 extra seconds to turn on the tap, apply liquid soap to hands and get hands wet so that Washing Washing with soap and water takes 20 seconds compared to additional hand washing exercises. They are equally made and solidly built (keeping in mind their intended use as toys). Highly recommended as a hand wash timer!
