Lifeproof ....waterspots and bulky.....hurled mine on the pond.
Life proof, no brainer for dog training. Had an otter box on my last one and when I upgraded last sept I took the otter box off and the phone looked brand new. Opted for life proof this time due to size and love it. Have not experienced any bubbles or any problems.
I have an otterbox armor series. People I talk to on the phone can barely hear me and I can barely hear them. They say it sounds like I am 20 yards from the phone will its on speaker. Great protection but the muffling of the sound sucks big time.
