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.

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.

Written instructions are quite good. However, I still messed up a setting. Made a phone call and easily fixed over phone. Only additional comment would be go slow on pressing buttons, especially the center button to move to the next setting, just be sure you're ready. Really love the detail book of instructions and the comments they provide, pretty funny!
Pros: Easy to install

Even though I read all the instructions in advance, I still had to go through the process twice before I got it right. In my honest opinion, the menu navigation is not intuitive and it takes some hunting around to find out how to get from one menu to another. I did highlight sections I felt critical on my first reading, but it was not a lot of help. I think this is a fine product and I'm sure I'll get better at it with future use.
Pros: Easy to install, Reasonable, Free batteries for life
Cons: Menu navigation not intuitive, Poor organization of instructions

I purchased their tire pressure monitoring system about 3 years ago and it has warned me, in advance of catastrophic failure on two occasions. Firstly, going down the highway, late at night, in the middle of near to nowhere, it gave me a “Slow Leak” warning. I was able to pull lover at the next highway rest point and top off my tire. When we arrived (in the morning) as a service area, I removed what turned out to be a faulty valve extension and the air loss stopped. The second warning was more serious. Coming across Montana, all of a sudden the “Fast leak” warning started flashing and beeping on the monitor. I had run over a small spike and it put a hole in my tire. Without the Tire Minder I would not have know to pull over and just kept blowing down the highway with one of my dually wheels just along for the ride! I feel that the system has paid for itself several times over in peace of mind and by stopping me from shredding my tires when they were low on air. Lastly, Minder Research has great customer care! When calling for a technical question about operation/installation or just to order fresh batteries, the people at Minder Research always respond professionally and effectively. You get to speak to a person cares about the question being asked, and is empowered to act giving you the response you need. I am very satisfied with their product and support.
