Great safety device,
Verified Purchase(What is this?)
This review is from: Tyre Pressure Guards 20 - 42 PSI (Automotive)
Every time you use your car etc a quick glance lets you know the tyres are at the correct pressure, I notice a slow puncture on mine and was able to change the tyre in my driveway, very convenient a lot easier than on the road, 'cause it always rains or snows or it's 4 in the morning when you get a flat so these are a potential life saver, highly recommended.
