This is a nice unit but I bought two and one of them broke within the first few days. The arrow does not return to "0" but gets stuck at "10". I contacted the manufacturer and they kindly sent another sensor I had within 2 or 3 days. I'm deducting a star due to an issue. Otherwise it seems to be a good sensor. Note that while the company is called "Rhino USA," the sensors are specifically labeled "Made in China." Do not be fooled!
