Mivizu Universal Windshield/Dashboard Car Holder Cradle for iPhone 5, Samsung Galaxy S3, S2, Note 2, Motorola Droid Razr HD Maxx, iPhone 4s & Vent Mount
For the money (at the time of purchase), nothing beats this. I'd recommend this to anyone. Its been stuck on my windshield for over a month, and so far the adjustable grips hold my Nexus 5 very well with a case on. (and its cushioned which is also nice for those who go caseless). Generally the spring-loaded mechanism that locks the phone in place is the part that wears out on car mounts. I don't expect this one to last forever but it seems pretty solid.
