Lifeproof Fre - fully submersible, "four proof" - shock, water, snow and dust (full IP68 certification).
So far I am very impressed - it doesn't add a ridiculous amount of bulk, so much so that I could easily use it as my daily case.
Why did I get one? Simple: I went on holiday with the kids and wanted to take photos of them on their body-boards in the surf. Not being able to leave them alone in the water, I waded thigh-deep and took my camera with me.
This presented a couple of issues...if my kids needed me, I'd simply have to ditch the camera and rescue them - losing not just the camera but any photos on it; and the issue of spray hitting the camera and potentially getting it damp and ruining it.
This made me think long and hard about maybe getting an underwater camera or housing...then I looked at the cost.
Simply couldn't justify a minimum of a couple of hundred dollars to replace a perfectl;y adequate point and shoot camera with a waterproof one that was slightly lower specced.
On reflection, I decided to see what was available for the iPhone - hence the Lifeproof Fre that i ended up with (normally $80-100 but I got it cheaper by virtue of it being the last in stock of the older model designed for the iPhone 5 as opposed to iPhone 5S).
My question to you, dear Geekzoners is this...
Do you have (or have you contemplated having) a waterproof housing or case for your mobile phone and do you use it?
I plan on using mine on my bike, at the beach and potentially at places like swimming pools etc. I plan to get snapping underwater pics of the kids etc.
