Unique Bargains Tire Pressure Sensor 433MHz Black for Ford Explorer

I got the tire pressure sensor for the ford explorer - and it is cute and little (see the attached picture). It did not come with instructions, but I am assuming (perhaps wrongfully so, as it is never good to assume!) that most people know how to use it. There's a small gray cap that can twist off- and it is made of plastic- but maybe a thinner (or cheaper) plastic than what is typically on a car or bike tire. There is another screw that is either metal or a hard plastic (is it bad that I can not tell?!?)- and there is the other part that is used to connect to the tire- in order to be able to read the amount of air pressure in the tires. I hope I used it correctly- but it seemed pretty easy and self- explanatory, and if you have a Ford Explorer and need a very small tire pressure sensor to carry in your car- then I would recommend this for you. Please note; however, that it is only for the Ford Explorer- so do not use with any other kind of car! Enjoy and stay safe out there ;).
