I bought this case. I'd read the reviews on Amazon, and was mislead that the phone still fits in the car dock even with the case on. It does not. I was also not impressed with the size of the screen protector, as I felt it didn't fit right. That said, I haven't even put it on, nor will I. But I unfortunately did tear it out of the box already and can't return it. It wasn't that expensive.
I have dropped my MAXX a few times. No scratches. I'm in a wheelchair and carry my MAXX in a fanny-pack sized bag that has my car keys, wallet and a couple other items. You would think that the screen is pretty susceptible to scratches in that situation. I have not had any problems, yet. I might decide to buy a sleeve as some form of protection for my MAXX.
I do throw my MAXX into my van when I get in, but only a distance of about 2-3 feet. I've dropped it 2-3 feet on a hardwood floor without any sort of problems. For me, as long as it survives that, I'm fine. I'm not going to deliberately chuck it over a freeway overpass just to see if it stays in one piece.
