The media could not be loaded.  TIP: inflate your tyres before installing and over inflate your tyres by about 2 PSI. As when you install them you do lose a little bit of air. Make sure you keep the spanner in your car for when you need to inflate your tyres.I bought these as I have a slow bead leak on one of my tyres and my car is a pre TPMS car. Which means i have to inflate it every month or so.This little gadget is great and easy to install.1) take off existing tyre cap,2) screw on security washer as far as it goes,3) put on correct sensor as far as it will go,4) wind back security washer onto sensor.5) use included spanner to tighten sensor onto security washer.6) test you can remove sensor by hand.7) repeat for all wheels.8) plug in monitor into lighter socket.9) it will take a minute for the sensors to connect to the monitor.You can then set alarms to warn you when your tyres reach a certain level.The only negative is you have to remove the sensor to fill your tyres, so don't lose the spanner and.keep.in your car at all times.

With winter coming we all know that are tyres we’ll change with the weather.So I decided to get myself a tyre pressure and temperature system so I’m able to keep an eye on what’s going on.I brought the type you plug into the cigarette lighter.I found that setting this system up is so fiddly and confusing using the instructions I had to turn to you tube.That said the system works well, the alarm sounds loud which can be heard over the radio.

It's too small to read it easily, the stalk to put it into the cigarette lighter socket is too short. I got an extension socket holder to use it more easily, but it's still hard to read. Hang on to the spanner to take the units off to inflate your tyres if you need to.

This is a really good TPMS for vehicles with a 12V outlet/cigarette socket. The screen shows clearly tyre pressures and their temperatures but I find it a bit too bright - at night the glow from it could be mistaken for you using your phone whilst driving. Great audible alarm for when a tyre has lost a certain amount of air. I don't bother with the anti-theft nuts.

If I had bought this device earlier, before getting a screw in my tyre, it could have saved me the cost of a new tyre.

Excellent tire pressure monitoring system. It was installed and tested. I am very happy with performance of ordered tire pressure system.

Tried to top up the tyre pressure and couldnt take the pressure monitor off had to bring it to the tyre garage and they had to cut it off. Such a waste of money 😡 😡 😡 😡

Absolutely perfect, does what it says and very accurate.
