Bought did three of these copies. I use it as a thermometer for the outside temperature around the house. The cable is therefore even South, even led north and west through the window frame to the outside. The first is appropriate for 2 years and still works perfectly. Now went through its third winter and can withstand the high temperature fluctuations and material from her, without prejudice. Looks small and delicate and unobtrusive, can be mounted or placed against the wall. All measurements that are important to me are possible, incl. The highest and lowest values in the year (just out of curiosity). To date, the white plastic is also not yet discolored yellowish how you experience it often, he's still really pure white. Absolute buy recommendation!
