They look like a good product but the problem is in the installation. You need a specialist shop with special tools to set up the sensor. If you go to TireRack, Firestone, or a franchised repair shop, it won't install it. They only install products purchased from the same place. Therefore, installation is not easy, and this is not a DIY project. And finding a special place is very difficult. My recommendation is to consider where you want to install them before you buy. And, most likely, you will buy them at the place where the installation will be made. My five cents.
