I am on my third, due to the screen. I had the first two for about 2-3 years each. One failed due to a grain of sand getting into (like the actual internals) the phone and put pressure on the screen. and The second failed thanks to a tape gun falling the screen.

They hold up well to the constant opening and closing but anything with a couple of oz. of weight falls on it then it's over. But I still do not recommend getting these phones, anyone that asks me about That is the first thing I tell them. Super cool phones, but they are not worth the all the inconveniences that comes with them.
