BLUF: If you're looking for an easy-to-use car mount that will keep your phone accessible and secured, this is the one you want.
I bought this for my LG G2 and it works great! I was a bit hesitant because the title says it is for "Select Apple iPhone Models" but there is nothing about this product that makes it specific to Apple (though I have no doubt it would do fine with an iPhone). The arm is adjustable in several places so regardless of where it's mounted you will be able to angle the phone for the best comfort / ease of access. This works easily with or without my case. Make sure you measure your phone before purchasing. There are two different versions of this mount. This one will accommodate phones up to 3" in width and the other one can go up to 3.5" for larger phones (or phones with very large cases). Best Buy sells the other one as "Vehicle Mount for Samsung Galaxy Note II." Again, though, there is nothing brand-specific about these mounts. They truly are universal.
I was a little concerned because my headphone jack is on the bottom of the phone so I feared that the bracket might get in the way, but it turns out that even the bottom bracket can be adjusted side-to-side and up-and-down so I was able to easily make it fit.
The one touch secure works great! Very easy to mount the phone and then remove it, even one-handed.
The suction cup is amazing! It grabs tightly to just about everything! If you have a very curved dash it may have a problem, but no more than any other mount. The suction cup feels very sticky, but left no residue on any of the surfaces I tried it on. The only downside is that when it comes time to move it, it can take quite a bit of effort to get it unstuck. For me, though, it's totally worth the inconvenience since it means that my phone will not move, even on the bumpiest of roads. After I moved it around a few times the suction cup did get pretty dirty and stopped sticking as well, but I just rinsed it under warm water like the instructions said and it started working like new again.
