【Big Screen】TPMS Solar Power Tire Pressure Monitoring System with 4 External Sensors LCD Real-time Display Car Tire Pressure Auto Alarm System Universal

Installation and setup was mildly painful, but with a little intuition and trial-and-error I got through it. I was initially very happy to be able to see the tire pressures on my 29' travel trailer (even if they all were reading about 10 lbs lower than 3 reliable manual pressure gauges showed. No problem: just know that when it says 50lbs it's really more like 60. The real problems stared about 50 miles into my first trip with the trailer when the warning beeper went off. Not knowing what the particular beep-pattern meant and driving in medium traffic with no way to read the manual at the time I pulled onto the shoulder to take a look. All 4 tires were firm so I looked at the owner's manual and the beep pattern indicated it had lost track of one of the sensors. So I went on my merry way. About 30 minutes later another warning that it had lost track of another sensor and then 20 minutes later another and finally 10 minutes later I had no readings from any sensor. Then, about 45 minutes later it started reading all sensors again. Story repeated itself over and over for that trip and 2 subsequent trips. I know it wasn't overly expensive, but the unreliability of it makes it pretty much useless since it won't show pressures for much of the time.

I just got these to keep an eye on the tire pressure of my van. All in all, it took maybe 15 minutes from unboxing to installed and it works exactly how I expected. One thing I did right away was change the Bar to Psi in the settings. Overall I cant attest to the durability or life span but my initial impression leaves me glad I made the purchase. It's comforting being able to keep an eye on tire pressure and and not take any of my dash space. The screen is also big and bright and easy to read.

This thing is at least 10 PSI off from my gauge. not even close.

This looked like a good unit when I ordered it. Once it arrived I went to program the high and low pressure alarms. I discovered the the pressure sensors are only good for 0-87 PSI. My trailer tires are 80 PSI tires so 87 is a bit close for my liking. The bigger issue was the the low pressure warning had a range of 22-45 PSI. With 80 PSI tires, I want to know when the tires get to 70 PSI so I can fix the problem. If I do not get a warning until the tire is down to 45, I could have serious damage before I know about it. Not recommended for High pressure tires.

Totally worth the money😁

The instructions seem to be for another item. It's referring to buttons to push that aren't present on this version.I tried to contact the company through their website but get no response. Without some kind of help, I have no choice but to return them. I say them because I received two when intended only one.It's disappointing since I liked the display features. Of course I will never know more about it's quality.

Been in my work truck for about a week, Comes on when i close my door or start my engine, Runs till long after im out of truck and has not needed a charge since my initial full charge. The solar charge feature seems to keep it full so far. I love the temp display per tire as well as the pressure reading. Seems to be VERY accurate. Thinking of buying another for my car even though it already has a tire pressure low warning. Would definitely recommend this over other ones i looked at if only for the auto on/off feature. The sensors are a bit larger then i thought they would be but does not stand out too bad.

It performs exactly as I expected it to do. The solar panel is enough to keep the display charged. The individual tire valve sensors updated the display within the first few minutes of your trip.I would not purchase again, just because it is a complicated solution for a simple problem. There is little to no change trip to trip. I don’t have a leak in one tire, so the display is not providing needed information. If I had a trailer, this would be a must to keep track of the trailer tires. I might take it off and bring it out for new tires or for longer trips.
