Takeaway: Easy to install and use, accurate readings, durable w/changeable batteries.

You'll receive the LCD display, four tire valve sensors, a windshield mount with ball joint, a 13' charging cable cigarette lighter adapter, a ball joint cigarette lighter adapter, two plastic gear wrenches, a metal nut wrench, 5 retaining nuts, and an instruction manual.

The sensors have a brass threaded side for screwing onto your car's tires. The LCD display panel shows you information about your tires like current pressure, temperature, and sensor battery life. The visible screen diagonal is 2" and the unit measurements overall are 1.75" x 2.5" x 0.5". On the right hand side are two USB ports (1A output) for charging your devices. There's a short barrel style plug that comes off the back for attaching to either power adapter. If you'll be using the ball joint adapter, the display will sit right above the cigarette lighter, but if you use the windshield mount ball joint, it adheres via a Velcro sticky pad to your windshield and you need to run the long power cable to your cigarette lighter; it's long enough for you to hide the wire underneath the trim in your car.

The plastic gear nuts are for disassembling the sensors so you can change their batteries. Unlike the TPMS sensors that came with my car, these sensors don't have to be replaced when the batteries run out and you don't need a tech to do it for you. The batteries used are CR1225 coin cells, and I'll update this review when one runs out so you have an idea of how long they last..

Installing the sensors took only a couple minutes. When I started up my car, the sensors took a few minutes to pair with the LCD display. I had to take off and reinstall two sensors before they would show an accurate tire pressure reading, but all the measures from temp to PSI appeared to be accurate when checked with a gauge and thermometer. Pay attention to the letters on the sensors when installing as they tell you which tire they go on e.g. RF = right, front (passenger side) and LR = left, rear (driver's side) etc. The sensors don't screw in all the way, so when finger tight, loosen the retaining nut back up to the sensor and then tighten with the metal nut wrench until the sensor is secured.

The display beeps and flashes when trigger thresholds are passed for high temperature and low/high pressure. You can change the settings be pressing and holding the 'Menu' button below the LCD and using the left/right arrow keys to navigate and modify values. You can also use the arrow keys to change the brightness of the display: low/medium/high. The only drawback to using this external system is that I need to use the wrench tool to loosen the retaining nut and remove the sensor in order to inflate my tires. However, it's pretty quick and the convenience of having the tire data live is worth the extra 5 seconds it takes to do this. When I take my car in for a tune up, I remove the sensors and put the regular valve caps back on.

Overall, the TPMS is able to show me important data related to my tires, so I can keep them well maintained and operating safely, for example, if I have a leak in one. It also shows the voltage level of the car battery as a bonus, and the sensor batteries can be easily replaced. It's easy to install and simple to use.

  1. I purchased the 6 tyre model. It displays the temp and tress fairly accurately, but all 4 tyres pressures are permanently flashing in alarm state. Also, cannot get the spare wheel to show up. Probably an ok product, but very poor instructions and no way to contact vendor for assistance. I'm still trying multiple combinations of programming etc in an effort to see how to get it out of alarm state. Tyres are at 48 psi which is quite within a normal range for a truck.

  2. You can change the threshold settings be pressing and holding the 'Menu' button below the LCD and using the left/right arrow keys to navigate and modify values. One value is the low trigger and the other is the high trigger (default max is 44 PSI). Just make sure to set the low value several PSI below your optimal and correspondingly higher for the high value. I'm not sure what the absolute maximum is, but I think you should be able to go above 50-ish PSI.
