I'd say that the first review was written by someone promoting Netatmo, as I found the experience vastly disappointing considering the cost. The setup was ok and not overly complex, but once it's running, it's quite finicky. I moved the indoor sensor after the first day, and expected the app to pick up the sensor again automatically, but I had to reinstall the app to pick it up again. The screens are not clear, and the graphs look very basic and though provide the basic info, they're not definitely designed for aesthetics. The only positive is that the sensors look nice.
