By mistake, I ordered at the same time product and thermometer La Crosse Technology WS9162 to EUR 19.90. I kept both and I could compare. Apart from the aesthetic (but that's purely subjective), everything is better (and cheaper) in this radio controlled thermometer "Wave" gray 17,94. First, the technology used is exactly the same (La Crosse Technology apparently), the batteries are founies for the "wave" gray (this is not the case for the La Crosse) and radio controlled time (option n does not exist in the La Crosse) starts up in less than 2 minutes and remains permanently accurate to the second. The temperature values provided are identical to 0.1 °.
