FOBOTIRE 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

Funcionan excelente

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.

Product as described. If customer support required excellent customer service.

In order to simply know what your tire pressure is via bluetooth this company requires you to create and account and require precise location tracking at all times. Utter garbage.

I've had some other pressure sensors that just did not work at all. The app on those were awful and they eventually just wouldn't work. These, though, do appear to function more like you would expect them to and the app is functional. Not great, but it works.While technically these are for "a car", I used them on two bikes. It would be nice if I could just have the app adjust to a bike vs a car, but you have to get entirely separate devices for bikes... but they literally do the same thing, there is no difference. Why not just sell these individually and make the app experience friendlier, and ask the user what purpose they'll be using them for? Just lazy development is my guess.Functionally they work as intended and appear pretty accurate. It's nice to get an alert when your tires are getting low, but be sure to adjust your pressure limits to get notified, otherwise your phone's going to freak out.

This is a really nice set of tmps replacement caps in the event your vehicle either never had tnps or you want to add it to something like a bike or motorcycle very easy to set up and it's a great value you don't have a much to set up to go through. There is no air leak as far as it goes they're very functional and the app works very well

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.

Installation is clear and easy with detailed installation from FOBO website; sensor quality is good too. However, the product performance is not as good as they claim. First the data refresh from sensor to iPhone device is extremely slow. It can be from 5 min to an hour. This is bad when you first start to drive off the vehicle and not able to know the tire pressure. Their CarPlay UI is extremely limited and will not do auto refresh to sync data with the phone app unless you keep use the back link at the top right screen corner multiple times. Even the refresh is not frequent, the battery still can't last for long. The original set that comes with the package least only 2 weeks. I install brand new battery (Panasonic) on all sensors, but just 3 weeks one of them already drained to only 2 red bars. However, the user experience is still not the worst; this lite product has a fatal product design flaw. Since the sensor reading/display must use the app in phone, if you forget to open the app in phone or CarPlay, you will never get any warning. I think FOBO should continue their original product that come with its own monitor, at least you will have constant monitoring of your tires. Bottom line, I don't think this worth $120 USD.
