TST 507 Flow Thru Tire Sensor - 2 Pack

2 years of fighting with this system for our 42 foot diesel pusher RV and Subaru toad, decided to put on our Trailblazer and 14 foot boat trailer instead. 5 of 6 worked from Minnesota to Florida in November. Sent them all back originally and they sent some back all tested, some worked, some didn't, the one closest to me on the driver's side steer wheel wouldn't read. Support is good, but still wouldn't work. Better things to do with my life...Kiss $600 goodbye.

This product worked perfectly. I have these 507 sensors on 6 wheels of my motorhome and I put them on my toad when we travel. They noticed me of a impending flat last year on my tow vehicle before any significant damage could occur. I will never travel without them.

Are not a replacement for the old 507 sensors. Will not mate with old monitor. Wasted $100. Could not give a 0 star rating.

I was using these on a motorhome. The transmitter would not fit in the opening of my wheels so that I could mount them on my valve stems. I had to return them. I bought valve stem extensions but they wouldn't work either. I returned them with no problem.

Have had no problems getting accurate air pressure & tire temperature readings while driving.

Sent them back for refund. One of them came apart the first time I tried to add air.

Good product

Great System, we put them on our RV and we are able to monitor our tire pressures with the TST Monitor and these Tire Sensors
