The Good: The temperature was reasonably accurate.The Bad: My first unit lasted 13 months and second failed after about 7 months.After that, I gave up and now just look out the window a my large dialanalog thermometer.The Ugly: Even when everything functions normally, the batteries last about 7months and it is an unnecessarily complicated procedure to replacethem. And, if you mistakenly put the batteries in with the polarityreversed, the unit is most probably ruined.
