I know there are many TPMS systems out there so I tried this product and so far I am very satisfied. I've settled on a system that doesn't use an app on my phone, I prefer to turn the system on, mount the display and don't stop there. Monitor and display are easy to read. It also comes with a suction cup. It has an internal battery so you can plug it in and charge it before use. I consider this a plus as I don't need another connected device with cables all over the place. I charged it up, attached it to the left side windshield and drove it for over 5 hours and it didn't even go halfway. It comes with a cigarette lighter charger so you can plug it in if you want/need. The device also has a signal amplifier that you mount on the chassis (or anywhere else). Very easy to attach and works great. Installation: I know this is one of the most read parts of the review. Well, it's SUPER easy! It took me more time to decide where to install the signal booster than to install and set up the entire system. When a product says it takes 10 minutes to install, it usually takes me 15-20 minutes because I read and read and doubt. This product says 10 minutes but it could be faster! You push a button to indicate which bus you're setting up, bolt the monitor to that bus, and it syncs. Repeat for each tire, then set a cold tire pressure recommendation so it knows when to warn you about low tire pressure. Very easy. Once he had all my tires raised he warned me that 2 of them were too low. I aired them out and we were ready to go. It monitors pressure and temperature and has visual and audible warnings. Overall, this TPMS was a great purchase. It's half as far as the price goes and honestly the price is worth my peace of mind on long interstate drives. Would definitely recommend this to my fellow campers, safe travels for all!
