Installation was successful and they seem to be working fine. I will update this review if any of them fail for any reason. Note that these sensors require a torx screwdriver to tighten the small screw that secures the blue plastic sensor to the valve stem. For me, I needed a very small diameter so I could tighten it in the right position for my impeller. You can also change them yourself if you buy the BeadBuster tool and watch the tutorial videos. I used XB-450 and it worked fine. You don't have to take the tire off the wheel or rebalance the wheel if you're just changing the TPMS sensors.
