This indoor outdoor thermometer is very easy to use and set up. I like the wireless technology, although the stated maximum distance for the placing the sensor of up to 100 feet away might be overly optimistic. I originally placed the sensor about 20 feet from the unit and then relocated it closer for better results.
Resetting the minimum/maximum setting is as easy as holding down the celsius/fahrenheit button on the rear of the thermometer for three seconds.
Two minor issues-
The sending unit is not waterproof, and needs to be protected from inclement weather. I eventually placed mine in the tool tray of my garden hose reel. The instructions suggested to placing it under a soffit or overhang, however a decorative little bird house would work well too.
In very cold weather, single digits and below, the manufacturer recommends lithium ion batteries for the sending unit, as alkaline batteries don’t perform as well in very cold conditions.
