After only nine months of operation, the window thermometer is already defective, the display only shows dashes, a battery replacement has brought no improvement. Even though the thermometer was reasonably priced, the short shelf life is disappointing. When a weather station from the same manufacturer of the transmitter is also turned out to barely a year service life, here I wait for a complaint to a reaction of TFA. A pity, because I was very pleased with both devices initially both by technology and by the optics ago.
Addendum of 23/06/2011: I thought that I will give a second chance to the thermometer and I've bought a second unit a few weeks ago, in the belief that the manufacturer would have learned from the reviews of the customers and improved. Unfortunately, I have a total failure once again, although the thermometer hanging on a window outside pane on the weather-protected and covered terrace and a maximum of splashing may have gotten. For an outdoor thermometer completely unacceptable!
