TST 507 Tire Pressure Monitoring System, 2 Flow Thru Sensors for Metal Valve Stems by Truck System Technologies, TPMS for Caravans, Motorhomes and campervans

Been using these sensors for over a month now and they seem to be accurate so far so good

They seem to work well. I would however make sure you use the security nuts that come with it. I didn’t and one of the caps worked itself loose. Lost air immediately in the tire. Once I put the security screws on we ran about 2000 miles with no issues

Good value for 4 sensors for the towed vehicle.

Much larger than I expected. Easy to install and they feel secure.

Product was exactly as advertised. And at better price than any I found.

Added to current system with six sensors Love security of monitoring all tires on RV and tow vehicle

Works goood so far

Bought these to add to a vehicle Im now towing behind my RV. They work as expected. However, be aware that they are longer and in my case stick out beyond the tire sidewall. Also, they use a different battery than the non-flowthru sensors. The battery is a smaller 1632 and I suspect will not last as long the 2032 installed in the non-flowthru sensor.

They work great bought them for the smart car. They programmed into the main unit perfectly. Since we tow now we can watch to make sure all ten tires holding pressure.

Easy to add to the main system unit. Gives good feedback on status of tires on towed vehicle.
