Good unit for the price
We bought this thermometer to use in our motorhome. we were looking for something that had a small outdoor sensor. this unit fit the bill and we now affix the sensor to the outside with a velcro strips so that when we leave we can simply remove the sensor and bring it inside. this eliminates any need for drilling holes. as far as we have been able to determine, we seem to be getting accurate readings both indoor and outdoors.
