Inaccurate: 72 minutes 38 seconds one way, 58 minutes 35 seconds the other way,

This review is from: Large Sand Egg Timer - choose from 12 time durations from 30 seconds to 60 minutes (Toy)
Good: The plastic outer and foam caps keep it safe from breaking.
Bad: Would prefer it smaller.
Using the stopwatch on my phone, the "60 Minute Sand Timer" takes 58 minutes and 35 seconds one way, and 72 minutes and 38 seconds the other way. The latter is 20% longer than advertised, far outside the "+/- 10% accuracy" claim.
They should make the sand timer work both ways!
