Bests & Worsts Reviews from Amazon

read or watch the instructions. i am in the engineering field and i can say i am very glad they made this cover. it fell out of my pocket and into a drum of 15w40 oil, all the way to the bottom. fished it out and worked fine, accidentally left it in a bag of tools throwing the bag around and it was fine. I was on my motorcycle through a monsoon using GPS and it was fine. my weekend adventures at the bar or club, spilled alcoholic drinks, fell into the toilet, dropped on the dance floor got kicked around and stepped on and it was fine. my adventure at the beach, skipped it on the surface and took videos at 7 ft (i lost track of how deep i was going, i would not try) and it was fine. snow boarding with my wife threw it about 25 yards so she can use the phone, missed the catch, ducked taped it to my leg to get videos while doing insane jumps crashing at times and it was fine. Road biking with my friends soaked in sweat and it was fine. i think the best one is being able to use a phone, search on the internet, play games, listen to music and not have to worry about dropping it or getting it wet while at an ONSEN( japanese public bath and relaxation) and it worked fine. as far as the jacks i don't know what ya'll are using but my car jack just plugs in. so hazardous material, alcoholic beverages, cold, hot, sand, pressure, impact, sweat, and my final one is dog grabbed it with its mouth and bit it lightly, covered with saliva, body fluids dog or human and it worked fine. its not indestructible but good God have some common sense even if you are as clumsy as i am.
