Cheap Slime 20089 Magnetic Pencil Tire Gauge with Aluminum Valve Cap - 2 Piece Review
I bought these because the tops of the tires that came with my new car was stolen and the replacement price from the dealer was ridiculous. These look decent if you only have the appearance of aluminum to chromium is a bit over the top of the wheels.
You get 8 of the valve covers and then two mini tire pressure indicators. The indicators work well, and read very close to the actual pressure in the tires.
The reason for the marked down a star is that one of my valve covers plasticscrew coating made inside broke, causing the lid to turn the valve only. Has not fallen yet, but it's only a matter of time. I just had this problem with one of them though.
Edit: I just realized that the photo does not show what actually plugs seem, including a client's image.
