TPMS systems Eez or Tireminder

TireMinder with the repeater since 2011. Normally cannot tire pressure does not register until I am rolling. Three flats over that time while on the road at highway speed and it alerted me to two. There was a programming glitch, perhaps human error, and one was not picked up. However, it has alerted me to high temp/pressure which gave me an opportunity to inspect and deflate, allowing me to continue on with no further issues.
