Review on Dsycar 12 Pack Tire Stem Valve Caps Black, Thin Blue Line American Flag Hexagon Shape Design, Premium Metal Aluminum Rubber Seal Tire Valve Stem Caps ,Universal Fit (Mini - Black Blue USA) by Kenkoy Braggs

First, I like the look of the caps.But, after being on after about one month, the set screws began rusting. I will have to apply oil periodically to make sure that they don't get stuck.Plus, the set pins are not easy to remove; it is difficult to find the Allen wrench slot. If they need to me removed at night or in inclement weather, it could be extremely difficult and frustrating,When I replace these I will likely get one without the locking set pins.
