The First: Can not connect to external sensor manufactured, No internal temperature indicator, extremely weak contrast.
When the replacement outdoor transmitter very power hungry, that is flat after 3Tagen battery. The contrast, however, was much better.
General: processing corresponds to the price, simple plastic in aluminum look. All in all ok. Another point of criticism is the battery cover, no clear spring contact for the negative pole but only two identical displacement contacts, nuisance grade if the batteries do not last long and you always keep the device into the light needs to recognize the Makierungen for pole -.-.
After my experience clearly -> not advise
Service from Amazon as always top.
