I forget my original suction cup in the rental car, so I thought this would be good replacement.I used it for one day and the suction cup already break into two pieces when I trying to put it on the windshield. It breaks just like the picture depicted by the reviewer "Dip" here. Because the way it was designed, there is no way to glue it back because it was held together by the perforated rubber.That's what you get for getting it cheap.So I got a real one from Garmin.
