Installed and used on a 2007 Ford Focus SES. The product is easy to install following the instructions. And worked well out of the box. I also liked the design. The only quirk I found was the accuracy. I used an electronic pressure gauge to check the tires for accuracy while inflating them. When I installed the product, I found that the difference between the product reading and the gauge was 1.0psi. Both the electronic sensor and the product were brand new. I found that to get a reading of 34.0psi on the product I had to inflate the tire to 35.0psi. Overall I found the product worked as expected and was fun to use.
