These Bluetooth Gadgets Let You Check Your Tyre Pressure Through Your Phone

It has a range of 30 meters, and you can monitor up to 19 vehicles at once. It has 3 different alert levels, so you can take action before your pressure reaches dangerous levels. It's manufactured by a Malaysian company, only takes a few minutes to set up, and has a security lock to prevent theft. A set of 4 costs just over £100.
