four good

The devices are simply recommended in 4-pack. The units as such I find it very successful and at the price that's a small sensation. (4.75 EUR incl. Shipping per unit)
Delivery was faster than specified, including top.
The devices convince myself easily.
Moreover, they are also easy to read. Had not taken me in advance based on the size information clear that these are somewhat larger devices.
The more I was pleasantly surprised when I was unpacking. They are easy to read even from a distance.
Nice is also the alarm and clock function. The date and time commuting in the display.
The only complaint would be the alarm clock function for Monday to Friday and not every day. That would make sense, because one would like to sleep on Wochenede times :-)

The devices You can also submit hang on the wall. That makes sense if you want to direct the focus more on the humidity of the wall. Especially for people with problems with mold problems on the walls, this gives an even better control function. Thinking of competing products such as the "Schimmelwächter2 the yes tenfold costs.

The cheap devices here are but amazingly accurate in the representation of temperature and humidity. If one every four units side by side, as they commute quite quickly on almost the same values. That's very precise. Of course, can not display on 1% exactly the same data as the other each device. There are indeed no calibrated equipment. In my practice test all four devices showed almost to the decimal place the same temperature and the deviations in the humidity differed by no more than 5% from each other. This is for those cheap devices just awesome!
I am extremely pleased and would not hesitate to recommend and buy again. Top!
