Negative Positive
Title: Works well, but consumes batteries.
Review: The temperature, humidity and atomic clock functions all work well on mine. I do recommend buying NMH rechargeable batteries for the base unit as it goes through regular alkalines quite quickly. Also, if you live in a climate with cold winters, the outdoor sending unit will sometimes not send a signal when it gets very cold. Lithium batteries seem to the best for the sending unit in cold weather.
