A pic of the unit sitting on the dash.
So far no leak issues. The sensors are not much different than the valve cap it replaces. Sure, I could get sensors to go inside the rims, but not for $25.As with the old-school red / yellow / green screw-on indicators, anything that holds open the valve on the valve stem to read the pressure can leave you with a flat tire. You can get non-OEM TPMS sensors, and the installer should be able to clone the ID numbers from your original sensors so the vehicle is happy.
