The ATOTO AC-UTP1 USB TPM is a great Upgrade to a car without a Tire Pressure sensor. We have a old camper van and forget always to checke the pressure or having different pressures on different tires. This tool helps us to be warned if the pressure is to high or to low.Here my short summaryPackage:- little box straight forward just the valves covers the usb adapter and a tool install the screws and a short manualInstallation- install the USB cable with the adapter to a free USB Cable port of your Atoto device- replace the valve caps with the valves with the sensor caps- the screws have to be put before on the valve, they are necessary as a luck nut for the valve cap- luck nut system is not that clear how to make it really tight- the valve caps have to screwed really hard down that the can measure the pressure - if not there is warning of no pressure in the app, have this in mind when you fill the air into the tire and put the sensor caps back- the sensor caps are a little bit bigger then the normal caps, i was unsure if they look to much out, but from the front of the car i couldn't see them, so everything is alrightFunctionality- open the preinstalled TPMS App and follow the instructions- you can set tire warnings for temperature and pressure (low / high)- the alarm is popping up automatically and you can deactivate it for a time or until you shut off the engine => great feature, that the alarm is not coming all the time- sometimes the sensor need to be updated or can not be recognized => switch off the Atoto S8 helps then or just waiting (keep in mind it is a wireless connection to the sensors)Summary- great additional Upgrade to my Atoto S8, i'm really happy to have the tire pressure at one glance on my screen- for me it is an essential security feature and i would recommend it- works great!
