I just installed it on my 2015 Ford Escape with a slightly curved winshield, and it won't budge I have to spend time to get it off if I want to remove it which is a good thing.It's large enough to fit a 10" tablet, and can be small enough to fit larger phones(6 inch screens plus)Would fit the larger iPhones, and Galaxy phones with cases no problem.The whole product is strong aluminum.Highly recommend if you're serious about purchasing a mount that won't let you down.Also recommend that you WD40 the threads on the screws when first purchasing for an even smoother experience.
