I am getting first hand experiences of how important this thing is............... last month I was travelling on the isb peshawar motorway and during the drive I didn't get the feel that there was anything wrong, at the toll plaza when I rolled down the window while the car was coming to a halt I heard something(and i really notice very small things in the car) and I thought kay shayad tire ho, so I opened the door and just looked at the tires on my side, but they were fine so I went on......... after around 2 km on the GT road, the car gave some pretty exciting jhatkas, and I had to pull over on the side, when I looked at the rear tyre of the other side, it was totally flat, and man it was a radial, actually it was loosing air throughout the journey and I didn't feel a thing, and bc of it going flat, the rim cut the tyre, and my dear original korean tyre was history ..........
And this week when I was going to the same motorway, I thought that I should get the air checked, and man I was amazed at the readings, air pressure in one front tyre was 60 pounds and the other 50......... I was amazed that how can the pressure be so much..... the tyre wala pumped out so much air and after that the ride of the car was much improved........
So I would say that this device sure seems to be imp when u get some experiences like this.....
Just that I don't have the budget to go for this now..... warna it's a good buy......
