the concept be without a doubt ingenious - take advantage of the CD slot to mount you phone or gp and keep you windshield unobstructed . just this week , I pick up the Samsung Galaxy note which sport a 5.3 '' screen . it be a behemoth in that respect . however , it be very thin - in fact thinner than the iPhone 4 . the only issue I see be that the retain ` ear ' could be a bit taller . I have a Speck Candyshell case on the phone which as case go be quite thin - some who have look at my phone do not realize the phone be even in a case . however , I find the phone sit a bit shallow in the ear which concern I when I receive the larger , more protective Reiko case -lrb- think Otterbox -rrb- .
