Its a very nice mirror and worked great for the first year. No loss of suction, never fell off. However, starting in year two, it would never keep suction. I tried cleaning the window and the suction cup; huffing a little moisture onto it prior to sticking, not huffing on it, nothing worked and so I went without a mirror. Plus you cant really make it go above your windshield, so it blocks some of the forward view. It was a quality mirror for the price, but now its in the give-away box. Will be buying a clamp-on that I can position above my windshield. So I do not recommend this product.
