I bought the Thermo / hygrometer 4 weeks before. The display has initially works well, but for a week, the digits of the display are no longer completely legible, since parts of the figures are no longer displayed. A reading is only by rates partially possible. The batteries I have replaced, because it is not, unfortunately. Unfortunately, now confirmed my assumption that this part is not worth much. After I was hoping that my first acquired Thermo / Hygro was a "Monday" measuring instrument, I've just bought a new one. Unfortunately, I can only confirm that this device does not tolerate moisture. It is, despite no direct spraying, penetrated moisture and it no longer works. This time, it has six weeks to work. Very annoying! I can only advise against this unit. Here fits the saying: Who buys cheap, buys expensive. Pity about the total of 20 euros.
