mine has lasted over a year, but my last one i dropped in water and it stopped working, i don't really like the phone but it seems to have lasted through all the times ive dropped it and stuff.
I also have the razr and it sucks but it is really sturdy, itz just really slow and u will start havin problems with ur charger and the usb charger port i wen thru 3 razr's and 4 chargers
I've had mine for 2 years, it is very slow. It has been an ok phone but I have only kept it because I haven't been due for an upgrade on my contract yet. I would not reccomend it.
