Reddit reviews LG G3 Body Glove Shock suit Series Case - Black

life proof are good cases if you have need of them, it's a shame they don't make them for more phones.

Your first lin isn't waterproof, and is very bulky, but a good case from the reviews I've seen of it, though you might consider something like a Bodyglove Shocksuit I've owned these, but not for this phone and they have given excelent protection.

your second link is one I've never seen, after looking around the lg g3 model seems fairly new but they've been making them for other phones. Those reviews are very good on the waterproof, but just ok on the build quality and sound quality. Get what you pay for I suppose since it's only $25 for an IP68 rated case.
