Device and buttons are easy to operate and roubust. Display is easy to read. The measured values appear to be very accurate. Have multiple comparison tests conducted both of the sensors with one another and with other various devices. Transfer to PC works without problems. Even after the transfer, the data remain stored on the device and can be read. Only when the memory is full, the oldest record is replaced with the latest. Will display the% share of not yet transmitted data. I find super resolved.
The software is practical but very simple. Unfortunately, it offers no graphics, but the data can be easily exported via CSV file.
The wireless sensors accurately measure and suitable terms construction and good sealing of the battery compartment suitable for outdoor use. The range is a separate issue. It's not just distance and intervening obstacles decisively, but often decides a minor correction location of the transmitter or receiver via reception or dead trousers.
All in all, convince the functions anyway: Whether switching between the channels - also in the history mode, slow or fast zapping through History values, min-max values for airing important dew point display, display any unusual sensors despite the fact that not shown on the display etc .... -> alles top!
