I have had my iPhone for a year and a half and my yellow/gray otter box cover has had to be replaced 3 times. At least once, I waited until it was practically broken to pieces before replacing it. I have friends with other colors and they don't seem to break as easily. At least 3 of my friends have had similar problems with this color and had theirs replaced multiple times.
The Otterbox - Commuter for iphone 4S was broken in the outer case. From the time I made the online warranty claim, I received a replacement within 4 days (2 of which were over the weekend). I love the Otterbox products and warranty replacement service. We have several in our home protecting iphones. You don't need to worry about needing to buy a 'temporary case' while you wait for the replacement to arrive since they get there so quick.
I had my otterbox replaced and within a month the exact same thing happened to it. Also my daughter bought a more expensive one that has the screen protector in it and it is coming apart..... Not to impressed.
I think that Otter Box has a great product for protecting phones. With this one I have been having trouble with the rubber around the bottom of the phone getting stuck between the phone and the outer shell.
This case is very nice, and more compact than the defender. I use it on a daily basis, It goes in and out of my back poocket nicely. It isn't as heavy duty as the defender (I also have), so it is good for everyday use. I have dropped the phone many times, protection is good, no damage to my phone yet! Thanks Otterbox!
The case seems to be of good quality and protects the phone.Even though we had a problem with the outer case cracking it was replaced with with in days in the mail.
