Seems effective to absorb moisture from the cockpit into mist that settles on my windshield (object of my purchase). Aesthetics, small and discreet. I have found that if absorb falls to the ground passing side, the windshield was fogged again. It is therefore necessary that the pad stays in place on the dashboard. To ease the daily, I recommend to fix it with double-sided tape, so he does not ride sandstone braking and acceleration, and there is no need to put it back every time we left the vehicle.
