This tool worked great on my 2015 Chevy Tahoe after I found the ideal spot for the antenna. I first tried placing the end of the antenna near the top of the valve stem but it couldn't communicate with the TPMS. I then tried to place the end of the antenna on the bezel at the base of the valve stem. Finally I placed the end of the antenna on the rubber tire at the edge of the rim and at the base of the valve stem. This position worked great for all 4 tires (see photo). I am very satisfied with this product.
