+ Very complete supply with battery, stand, double-sided tape
+ Processing anywhere good (rubber seals, stable stand)
+ Large, easy to read display, humidity in the first place
+ A lot more detailed information on the base station (sensor location, temperature, time, battery level, etc.), well-structured
+ Clock that set up properly
+ Outdoor sensors act really good weatherproof, were easily recognized and can be expressed by name.
+ The software (downloaded from the Internet!) Could be installed without any problems on Win XP and Win7
+ The data transfer via the supplied USB flash drive to the computer also works well
+ Values seem to me to be exactly (I lack a reference instrument)
+ Also on the device itself, without using a computer, the values can be retrieved
Many features I have not yet used (dew point, min / max values, alarm thresholds) - the camera seems to be applied to me on a professional use.
The only drawback I find the software that is a bit confusing: The data representation is hardly changeable and lacks a graphical display, you have to go the environment through the creation of a CSV file which can then be imported back into Excel.
Overall for the price a really good value, so 5 stars
