Amazing device. I would not recommend using the app while driving... let a friend drive, and watch how the tires respond to what you're doing. No big deal perhaps if you've got a modern car, mine is much older, and probably been running at the wrong pressure, like, forever. Three were too high, and one was 1/2 low, it was pulling, I should have known, but, I'd never guessed the degree it was off. Now I can watch the temperatures, as well, and one can definitely see that relationship to pressure, and again, to what you're doing. Their app has two other devices, neither of which I'd be interested in... EXCEPT for the fact that this works so VERY well... the other pieces almost become a must have. Oh, must have duplicate sets for other cars in the family. Excellent gift! Too bad they don't work for a motor-home. Once you see how well they work for what they were designed for, a car, you won't want to drive without them.
The smart tire safety monitor by Nonda has been an awesome product that in my opinion offers a lot of helpful information. I am by no means a car junky, but I do like to take care of my car. Many of the newer cars come with or have an added package for things like pressure monitoring but on my 2013 Ford Fusion, I have no idea how my tires are performing until something bad happens.
First I'd like to say that the installation of this product was incredibly simple and I had no hiccups whatsoever while getting it set up. It comes with security locks though I don't know how well those stand up to stopping somebody from stealing them. All of Nonda's products sync conveniently with their app which is clean and easy to navigate. The product shows me the tire temperature as well as pressure and keeps a log of changing conditions which you can see in an easy to read chart.
The biggest flaw with this product, in my opinion, is the LED indicators on the hub. While it is cool that the hub looks like a car, there isn't an easy way to see all 4 indicators while driving no matter how you mount the device. The reason I think this is such an issue is that the LED's are meant to be the immediate indicator of an issue. Because I would not be using my phone while driving, the only way I'd know if there was a problem with the right side tires is if I had a passenger who could see the 2 LED's on the right side. I will say though, I especially like that they included a front-facing USB port on the hub so you're not losing a USB port by using this device.
Another thing I must commend Nonda on is their packaging, I know the packaging can be considered irrelevant but I think it is a nice touch. Everything is packaged cleanly and compact making it feel like a quality product, which it is.
As my title states this is a disappointing TPMS system for cold weather climates. Users that have given this negative marks are just in their feelings as I was too. Nonda has at least tied to remedy the issues with non-corrosive sensors; however, this solution does NOT resolve the issue as on extreme cold-weather conditions this product fails. I have gotten around this a bit by treating my valve stems as well as the threading in the tire sensors with "special" lubrication. You can find this product for rust-proofing and corrosion in other hardware stores. AGAIN, you MUST TREAT the threads of both the valve stems and sensors at LEAST three times a month IF YOU ARE IN COLD-WEATHER CLIMATES! This prevents the MAIN issue that I and many others had suffered from this product. It's understandable as with ANY electronic product being introduces to extreme cold weather. I still have not found a more intuitive TPMS that alerts you when your tires have a slow leak as effectively as this one. I will say that If you have newer car models (i.e. 2019 Honda Pilot [Touring or Elite], 2020 Honda Accord, 2020 Toyota Camry, etc) you WILL NEVER NEEDS THIS UNLESS you wish to have SLOW LEAK DETECTION. I honestly, cannot wait till the rest of the automotive industry keeps up with Audi and BMW technology as they have this covered too. This is my second set of Nonda AccurateTemp TPMS w/ Corrosion-Proof Sensors. I did have to have my dealership use a "special" compound to remove the sensor AGAIN; however, I did neglect to put the required lubrication on before I applied the sensor. What i DO BELIEVE is that Nonda should warn cold-weather users to use a solution before applying their product. As a matter of fact they should INCLUDE specific compound of lubrication with this product as well as offer it as a Amazon consumable (sorry I don't remember what you call their auto-order products). This way we wouldn't se a negative review. Nonda please correct this as you have people that honestly like your products.
After several months the only issue I have had is that the app is a little confusing to me. While you need a cellphone to set up initially you have the green lights in the USB plugin unit and a sound alarm to let you now if your/the preset pressures high and low are crossed. It reacts quickly in real time to alert you of a blow out or rapid loss of pressure. I verified the pressures against a high quality tire gauge and they seem fairly accurate within 1 PSI. CR1632 batteries can be changed in the sensors. Hopefully the batteries and sensors will last.
I’m lazy. I should check tire pressure more often than I have in the past. With ZUS, I check all four tires every time I start to drive. I also leave the app in the background on my phone in case I start to hear funny noises - one look at the app and nope, tires are good.
Except for one day headed down the freeway a little faster than a highway patrol officer would approve. As the pressure receiver started to buzz, I got a pop up message on my phone that my left rear tire was losing pressure. A quick look at the phone app showed 25 pounds. I quickly headed across four lanes of light highway traffic to stop on the shoulder. The last thing I remember seeing was 17 pounds of pressure which quickly became 0.
Not fun to change a flat on the side of the freeway in Phoenix. But, I got off the road before destroying my tire. This $100 gadget saved a $200 tire.
Disadvantages - none of which now matters to me - pressure is displayed in incriments of a half pound. Three times I have had a leak attributed to the valve stem or pressure gage. Last time the tire store manager suggested replacing all the valve stems with metal ones. So far that has solved that issue. If one of the tires seems a little low, I drive for an hour before getting worried. The pressure update rate seems slow and a low tire will be good soon. Since tire temperature is also displayed, I know the pressure isn’t rising due to the tire heating up.
When it came time for this device to do its thing, it worked immediately with multiple types of notification. Very pleased with the function. Bought a second unit for my wife’s car.

Saved my butt when my tire was leaking air, and my car’s sensor wasn’t calibrated... especially when you have work the next day. Save yourself the future screw job, and get it get the tire pressure to the point, and see if it increases or drops almost live on your mounted phone
Installed this last weekend for my wife. I suspected a slow leak in her left rear tire but the drop was seemingly negligible. Last night the system alerted her to tire was low again. A trip to the tire shop identified a screw was embedded in her tire. All repaired and good to be back on the road, this early warning saved her from running flat and being stranded somewhere. Thank you for a great product.
This works as advertised. My only reason for 4 stars instead of 5 is the sensors often miss reporting in and the receiver is beeping for a missing sensor, but then it's detected in the next reading loop. I would suggest they increase the timeout before a sensor is declared MIA.
The sensors are very easy to install and setup with your mobile phone. Once install, the sensor and receiver will auto calibrate the pressure and temperature. Pressure readings is pretty accurate when i compare the reading on my phone with the meter pump at the petrol kiosk. In fact one the second day of installing this sensors, it let me know that one of my tires is leaking air and upon checking, there is a small pen knife blade stuck to the inner side of the tire which is otherwise not able to detect.
One hassle is that when you want to pump air into the tires, you need some time to remove both the anti theft nut and sensor. otherwise, this is a good product to have.
Nice addition to any car without TPMS. My car does not tell you the actual PSI, just a warning. This gives you not only tire pressure, but temperature and charts it so you can see when pressure fluctuates with temperature. Very fast installation and an added piece of mind.
