Review on TST 507 Tire Monitoring System: 4 Sensor with Color Display - Perfect for Tracking Multiple Trailers by Robert Aiono

This TPMS is probably the best or one of the best you can buy. I just used it on a weekend trip last week and it worked as expected. I went to YouTube and watched some videos on programming. I just learn better from watching manuals than reading them, although you should read them anyway. Would buy and recommend this system again at any time. This is an update to continue. It worked but wasn't consistent. Sometimes he just watches two of my tires and then one. I didn't know what the problem was so I bought new batteries. He still only checked three tires. After driving all day, the a6 reached its destination, after which it began monitoring all four tires of our trailer. So there is no jury yet. I might have to stay until he has all four wheels. Sequel follows.
