The sensor was much cheaper than the OEM, but the lower price comes at the expense of the need for small adjustments. One of the screw holes was too small and had to be filed to get the screw through. The cable clamp was also the wrong size and had to be replaced with a factory clamp to tie the cables together. This added extra time to what should have been an easy installation. I think you get what you pay for. The device works fine and fixes the problem. Longevity remains to be seen.
