Am sooooo happy with the purchase! ! The are made safe thanks to a backup facility of transparent plastic, so that the clock does not break, even when on the tile floor of the small hands fall down (:) even if it is to happen more often). They are about 10 cm high, colored sand is clearly visible (top and bottom). From the use ... I can only recommend it! The 4-year-old has understood so immediately the opinion of the time. A few days after he sprichte of hours and minutes already with full understanding. To clean up, go to the bathroom instead continue playing 10 minutes before the Kika KiGa go look .... for everything are now used and the kids do it yourself with pleasure. Mussmann just be careful that the sand (the very fine is) really started to run. When run it is not as noticeable because he is so small. So for me it is time to pass a just and with a clock only in full month that the sand has not begun to run. I quickly noticed.
