I had it for about 1 1/2 years--every time I went over a bump something would rattle from the passenger side. Today I was sitting in my car on the right side and as I pressed on all the cheap door panel, dash, etc. I had a hunch that maybe the cheap plastic that runs along the windshield and front window was rubbing against the dash. First I tried to wedge some paper in-between so they wouldn't make contact. The paper slipped in the crack. Then I drizzled some Armor All along the crack, wiped it, and did it again. Voila--no more annoying rattle.
