Bought 2 of these for temperature checking in garage, workshop and trailer. The Bluetooth connection works well up to a distance of about 25 feet through exterior walls and the metal sides of the trailer. The only thing I would wish for is a PC app to keep an eye on the temperature in addition to the Android app.
