Teacher Created Resources 1 Minute Sand Timer - Small (20646), Red, Pack of 4

Muy útiles para trabajar la espera en niños.

Les sabliers sont solides et fonctionnent super bien! Excellent produit!

Works great. I got these for my daughter for brushing her teeth, we mostly use the two minute timer. These will definitely last and I lover the bright colours.

Although very toy-like, at around $1.24 each, these are good enough for their purpose. The glass timer is inside a plastic tube, attached to plastic stand ends. I wouldn't expect them to break if they hit the floor, but stepping or sitting on it likely would. The time is printed on both ends and having them colored is nice, especially with the 3-minute timer since you can barely read the white print on the yellow end caps.Like most sand timers, don't expect total accuracy, but they all come close enough to their stated times. I tested all four multiple times, and while the speed varies with any given use, they all finished within plus or minus 10 seconds.However, I've found the 1-minute timer sometimes gets bottle-necked and stops. I haven't noticed this with the 2 or 3-minute ones though (don't really use the 5-minute). I only use these when lifting weights to time my rest in between, so it's not that critical, but something to take into account if the timer isn't in constant view. Otherwise they're still worth it for the price and function.

Works great to help the kids wash their hands long enough!
