Great service from Truck Systems Technology(TST)

I purchased TST Mode TM-507SG flow through tire pressure and temperature monitoring system. two years later when I had trouble with a sensor, I called them and got outstanding service. Only a couple of days after sending in the sensor and got a phone call about the test results and suggestions on correcting the problem. The TST representative was very friendly and knowledgeable about the monitoring system. I wish all companies were this customer friendly.
