FOBO TIRE LITE TPMS Sensor - Wireless Tire Pressure Monitoring System with Bluetooth 5.0 | Real-Time Tire Pressure Sensor | Easy DIY Installation for Car SUV & 4x4 | Compatible with iOS & Android

I'm very impressed with these wireless tire pressure sensors. My tpms monitoring is always giving false alarms on my car dashboard and I ordered these just for peace of mind. Its super handy being able to just pull up the app and double check each tire's pressure. Installation is pretty quick, simply pull the tab on each sensor and replace the tire stem cap. I'm not really worried about them getting stolen so I didn't install the optional locking nuts for each one. The app recognized each sensor straight away and it seems to be pretty accurate (within ~1-2 psi). No complaints, this is a great addition to help me keep track of my tires especially when the weather is still swinging almost 20 degrees each day.

I'm glad I got these! Let's start with the "not-so-good" (but not-too-bad items) since most issues were with initial instructions and app installation steps:It was confusing, and it would have been easier if there had been QR codes for the specific Android or Apple Store applications- or even better, for the user manual, which would have made things easier. Once the app was installed, it was easy to add each sensor. The app suggested scanning the "QR code on the package" to assign all four sensors simultaneously, but none of the scannable codes on the packaging worked. Each sensor had to be added one at a time, but even one at a time was pretty straightforward.The package came with some "locking nuts" and a special-purpose tool. However, it wasn't until I found the owner's manual in the mobile app that I understood how they were supposed to be installed to deter (certainly not prevent) theft. The only other slight con to this is that filling the tires means having to loosen the lock nuts with the tool. Fortunately, they provide two, so I keep one in the car and one at home in the garage.The only other concern is the number of permissions required for the app. Some of them were understandable, but others, like "Location," just made me feel like it was yet another app revealing my location and whereabouts. During the initial application install, it allows you to "skip" some of the permissions -- but when you go to install the first sensor, it requires you to turn on all the permissions anyway, basically.Ok -- the good parts:Our vehicle has a TPMS, but it only indicates that "a" tire is low, but not "which" tire is low. I like being able to see each of the individual tire pressures. The app also has a nice "overlay" option, essentially a very compact view of the tire pressures that float above any other applications and can be repositioned anywhere on the screen. Tapping on the overlay makes it even more compact into a single button. This makes it easy, for example, to overlay on top of the navigation app so you can monitor directions and tire pressures -- I am looking forward to this on the next long road trip.The lock nuts, which slow down someone wanting to take them off, are helpful, and it is nice to know that even if someone takes them, they are unusable unless your account "releases" them. Now -- if the location requirement would report to me who stole them, that would be great.Overall, these are a great add-on to a vehicle that doesn't have specific tire pressures, and I feel much safer taking road trips and seeing potential (or actual) leaks in real time before they become an issue. I'm also more apt to keep my tire pressures in good and well-balanced ranges, avoiding alignment or wear-and-tear other problems because I can quickly see all four tire pressures without having to take off caps, use a portable gauge, with unreliable readings, making it all too easy to skip this easy safety check.And, if I change vehicles, they can come with me. I think these are a great investment.

These tire sensors have made a huge difference for me with all this Florida unpredictable weather. I've been dealing with crazy temperature swings (85°F one day, 50°F the next morning), I was tired of constantly finding my tires underinflated during cold snaps or overinflated during heat waves. Putting it on was easy, I just removed my valve caps, pulled the battery strips, and twisted these little gadgets onto my valve stems in about 10 minutes flat. I really like watching the real-time pressure changes during our weather fluctuations, last week's cold front rolled through and I actually watched all four tire pressures drop simultaneously on my phone screen from the comfort of my living room. The accuracy is spot-on too; I've double-checked against my trusty manual gauge multiple times and they've matched perfectly every time. They stick out a bit more than regular valve caps, but that minor aesthetic issue pales compared to the convenience of checking all four tires with a quick glance at my phone instead of crouching in the Florida humidity with a manual gauge every week make it worth it.

I was really excited to get these TPMS monitor sensors for my car. I followed the instructions and put them on my car and nothing happened. I will note that when you first scan the QR code that's put in the packaging it takes you to a website where it asks you to verify your identity by putting in your credit card Of course I did not do that so that's kind of a red flag. Instead what I did was I searched for FOBO TPMS in my Google Play app store and I was able to bypass that. I don't understand did I have to put in batteries? I always thought they came with them already like it's very confusing. I really wanted this to work better so if someone could please let me know what step I might have missed that would be really helpful cuz I would really like to rate this higher.
