I have my first ISS together with anemometer kit and leaf-soil station now for four years. Recently I had to replace a broken temp/hum sensor and the rechargeable batteries for my 24h aspiration kit. Never changed other batteries for those three stations. I bought a ‘spare’ ISS two years ago as a replacement for my broken TFA Primus/Opus station. And the funny part is: four months a year the sun at my place goes from east via north to west, so the solar sensors facing south don’t get any direct sunlight that period!
