since two months now I use the weather station. The start-up and software installation was very simple. Everything worked right the first time. To this day, there was not the slightest disturbance and no problems. The supplied batteries still hold and the wireless transmission of data via USB flash drive to your PC runs flawlessly and been absolutely flawless. The software is very reliable and gives me clear all the data I need. I'm really amazed at how comfortable I can now more easily read the indoor climate all my rooms at the weather station and the PC ... The four transmitter and the receiver (weather station) are very valuable and properly processed well from my feeling. The radio transmission between the transmitters and the receiver works flawlessly with no errors (with me the TV channels are different 4-12 meters from the receiver; - depending on the room location, the radio signal penetrates here in the massive old building always easily 1-3 walls). I'm curious still at first sure soon forthcoming battery change of receivers and transmitters. Furthermore, I can now but unfortunately not report! Amazon had as always delivered quickly. The packaging was perfect. Greetings
