As fanatical tea drinkers I am excited about these hourglasses. Finally the teabag time can be accurately controlled. Especially the 3min and 5min watches are constantly in use and come with guests always good. Only in 7min clock of sand gets stuck sometimes. But since I do not drink tea with this pull-time bothers me not. I just also a set for my mother ordered for Christmas, because she finds the watches also great
