So far so good! I bought all 4 and synced the sensors to my 2007 Nissan 350z TPMS. It should be noted that each new sensor comes with a white/almost transparent plastic ring. I didn't use it, it was the only part I missed when installing these sensors on each rim/wheel. And as long as the air stays in the tire. If you have any questions about 350z TPMS activation, let me know. It's not that hard once you get instructions.
