I ordered this little hourglass, for brushing teeth, for my son (4 1/2 years). Now toothbrushing has thus become a real event. I would only expect that the hourglass had a little more carefully and above all just bonded. In addition, the length of time the hour glass is just two minutes. Too bad, because actually Solte you brush your teeth three minutes yes. But anyway, I do not regret buying these small hourglass not, because now there is no struggle at bedtime, because of toothbrushing. And that it is I really value.
