I purchased this system after reviewing comparisons and a presentation of two different models at a rally. It is easy to set up and use. It monitors temp and PSI, batteries are replaceable, monitor charge lasts for a month and is small and portable. Readings are during travel. Sensors auto turn off to save battery life so readings BEFORE travel can be done if you pull your rig out of storage or move it some before actual travel. Great system.

I purchased this for a fifth wheel trailer to monitor tire pressures. We had experienced two tire failures on different trips reulting in RV damages each time. I feel certain that if I had this product there would have been adequate warning of impending tire failure. This product works as advertised to monitor tire pressures and temperature. This is a great product and definitely worth it. Easy to install and setup.

Works well, but has a flaw

I purchased this for my travel trailer before a 14,000 mile, 10 week trip to Alaska. Installation and setup is easy and it functions well. It was great to be able to monitor my tires on the rough roads to prevent damage to my trailer. Part way through the trip the charging connector on the receiver separated from the circuit board, so I could no longer charge it. I wasn't too surprised since the connector never really felt solid in the first place. When I got home I contacted them and sent it in for replacement. They have great customer service and I received the replacement promptly. The replacement unit charging connection doesn't feel any more solid than the first one originally did, so I will handle it carefully. The micro USB connector they use is a good choice, it's almost universal on small electronics. In this case, I think they need some design revision so the connector is more securely attached.
