Great build quality, and holds my 5.5" phone (Oneplus 2) just fine. Also it's worth paying extra to get this mount, vs those other ones you can get for like $10, as the rubber on them rub away and you end up putting metal bars into your vent, leaving behind scratches. So far the Belkin mount is still in as new condition, and feels like it's been built with higher quality material, so hopefully this won't happen, and even if it does, these come with reliable warranty.
