Unfortunately, after 2 years of ownership, the sensors no longer work. In the beginning they worked fine. Chased her through the desert sun and winter snow. They would randomly turn on and scare me to death with a certain bump or motion detection with a very loud and obnoxious alarm sound. Installation was easy, literally putting sensors on each tire and setting the reading on the main screen. And the battery was always charged via the solar panel on top of the dash. It looks like the product has been redesigned so I can't speak to the actual model. I hope the problems I had with the old model have been fixed.
