Review on Enhanced TST 507 Tire Pressure Monitor with 4 Cap Sensors and Vibrant Color Display for Optimal Truck System Technology Performance by Eric Hartman

I bought this to keep an eye on the tires of a 38" saddle bike when I travel this summer. It's easy, if a little tedious, to install, but easy to follow if you follow the instructions. Setting an alarm is a learning experience, but again, a little trial and error is required. I only use them on four trailer tires. Although they work as soon as they are detected, when powering up the system I had to take multiple paths to get the pair to power up from time to time. In particular, one of them could work for half an hour or more, or not turn on at all until the next reboot and then work fine? It seems to match my two tire gauges fairly well, but the temps are nowhere near the infrared temp gauge. Of course, the gun reads the cartridge case and the gauge reads the air, which might explain the difference. I always hit the tires and hubs when I stop so it's not a problem. It's also interesting to start at 60 degrees and then start with puberty. It doesn't take long to figure out where to start. I only have about 3,000 bugs on them, but overall it's a worthwhile addition that will help us stay safer. New date. Well that seemed like a good idea. And I drove about 3,000 km. Then I closed it while I was working in Dakota for the summer. When it came time to return to Arizona, I turned it back on and nothing. I replaced the "two year old" batteries and was able to reprogram four sensors. Literally went through the whole procedure, pressed "back" twice and waited for her to appear. Nothing. maybe after I start riding the next day. Nothing. Picked them up and reprogrammed them twice more that night. you guessed So an 1800 mile trip would be without the paper weight of a few hundred dollars. This is money I'll never see again. Maybe they will work for you, they will work for others, but I would think twice before buying them. Last update. Although I decided it was a futile effort, I figured I'd give it another try as I'm about to drive a few thousand miles for a summer job. Pick a few stations and walk through the process. He accepted and showed the IDs, pressed back twice and waited for the display to read. And waited. After checking a few times that evening but still being unreadable the next day, I just resigned myself to not having $300 left and put it in the box.
