As a techie and lovers of electronic gadgets, also of interest to the climatic conditions in my bathroom and the well time ... I needed a unit that all these demands. To keep it short, positive: DCF reception well, very easy to use, simple design, processing well, segment displays large enough Unfortunately, I feel negative: relative error of measurement in comparison to my Oregon Scientific RMR 500 -5% Humidity + -1 ° C temperature, segment display has very low viewing angle ie when the angle of view can no longer be read from the display deviates too much from the vertical. On the whole, but I would buy it again!
