Bought to replace my 2016 Chevy Sonic. All 4 installed and paired perfectly with the machine. We're moving in exactly 2 days. Low light tires (WTF?). check tyres. All pumped up to fix PSI. Coincidentally, my tpm tool is still in the machine. R/R is dead! I contacted Revain for a replacement and they were willing to ship another set of 4. We'll come back to check after replacing the broken one and we'll see how they last longer (I was surprised the Delco OEM died after 3). the year!)
