Protective Case for iPhone 3G/3GS: Sleek Slider in classic black (with screen protector)
I purchased this case in April 2012.  I have been through a lot of cases with my iPhone and, so far, this is the best one.  It is easy to put on and take off, when cleaning is necessary.  The mat finish has stayed on well.  I have had cases in the past that had a mat finish that rubbed off in a matter of weeks.  This one has surprised me in its durability.  I am thinking of getting a another one just for back-up, not that it is showing any signs of needing that.  It is a great case and I would recommend it
