Wireless Tire Pressure Monitoring System with 4 External Sensors, 5 Alarm Mode, Real-time Displays Pressure and Temperature, Bluetooth 5.0 TPMS, Supports Android and iOS

These are great to have. Simple setup. Easy to use. I plan to use them on my trackday tires. The app works like a charm too.

The pressure sensor itself seems accurate but everything else is just... Bad.I bought these to have access to info on my phone screen instead of my current tpms thats attached to the 12v outlet. Here is my experience:1. One of the sensors was dead on arrival ( rear left if that matters)2. They feel really bafly constructed compared to my existing sensors. The plastic has a brittle feeling and there are a lot of sharp and rough edges.3. The app does the bare minimum and sucks at any kind of error handling. Two of my tires suddenlt showed up at 672.4 C - which I am sure is at the melting point of most alloy wheels. The worst part is there is no way to mute the notifications. They just keep sending a new notification every second. Only way was to close the app and ignore it. I stopped the car to double check and the sensor was vool to the touch ( it was about -4 C outside)Basically a lot of quality control issues and bad UX on the app kills this product.

works great with the app. the anti theft nuts dont stop me from unscrewing the main item. tire pressure seems accurate.

A pressure sender caps is a good idea, but these are too big to be installed onto my wheels. There is not enough space between the valve stem and the rim to accommodate the cap’s large diameter. Therefore, I can't install them.

Junk, Two units wouldn't pair to my IOS, one reads Temp wrong and one works as expected. We are involved in a large trailer renovation project and I missed the return date by 2 weeks. Junk

Product didn’t not calibrate to app. Only 3 out of 4 worked. Would not recommend.
