Samsung Galaxy S3 Defender Series Build Your Own Case

Enjoy 50% Off Samsung Galaxy S3 Cases

OtterBox.com is the only place you can go to build a custom Defender Series Samsung Galaxy S3 case. The Defender Series offers 3 layers of protection so you don’t have to fear the inevitable oopsie or accident. The two piece polycarbonate inner layer snaps together around the device to form a secure foundation. The inner layer includes a built-in screen protector that prevents scratches while memory foam pads cradle the device to provide added shock absorption. The outer layer is made up of rugged silicone that wraps around the inner layer to absorb impact. The Defender Series Galaxy S3 case comes with a ratcheting belt holster that can also double as a viewing stand.

Rated 5 out of 5 by Dog Teeth I love my Otterbox Defender. I drop my phone continually. Its just something I do. The Otterbox Defender has been wonderful. Yesterday, I dropped it and didn't realize it. Well, it doesn't survive dog teeth. It has kept my phone scratch free and bump safe for a year now, but it could not survive my dogs teeth. I will purchase another one, once I figure out if I am fixing my current phone or buying a new one. November 19, 2014
Rated 3 out of 5 by So So at best Though the case has protected my phone the rubber outter portion has not stood the test of time. Beside the fact My SQURAE wont work with the case on. The tabs quickly broke off and the case became enlarged and worn out. When I asked about the Guarantee, I was told they stopped giving free replacements. "Just my Luck". I am hopeful the next generation is more durable. For this kind on Money you would think you were getting a better quality product. Tossed it in the trash this morning. August 25, 2014
Rated 2 out of 5 by Very Unhappy with the Colors My review is more about the disappointment of the color represented online and the slow delivery. We paid extra for Fed-Ex 2 day delivery. The item was ordered over the weekend and we did not receive it until Thursday. We placed two orders the same day (from different companies) and selected 2-day shipping on each. The other order arrived on Tuesday and this one finally made it on Thursday. I wanted a very masculine case for my son who is beginning college. We chose the gunmetal gray and the picture of the color on the online was/is so much darker than what we received. The color of ours was a light gray and it did not have the masculine appeal we expected. Very disappointed. Also was not happy that the orange piece that went on first was already clipped together and we spent so much unnecessary time trying to get it apart to encase the phone. Too bad it did not come as two pieces. It was extremely difficult to get apart and took two people to get the job done. I would most certainly return it if I had the time but my son needs it for college and I could not return it and purchase another one in time. I will pass on Otterbox. Not sure how it will protect the phone. Does not feel or appear as strong as I had hoped. August 14, 2014
Rated 3 out of 5 by First Time Otterbox Customer I received the Defender series box today and installed. The pictorial instructions were less than desirable. When putting together the inner protective shell, I noticed that that one of the clips was broken. It's obvious that this will not be a case that I would want to open and close on any frequent basis. Over all, it looks like it will protect the phone during minor drops and bumps, but looks too rigid to absorb any major drops. August 8, 2014

The belt clip is ABSOLUTELY available. If you don't want a clip, go with the armor series.

In order to order this case the build your own it comes with the clip. Obviously the clip is out of stock. If you don't use the clip put it away or sell it to some one that have the same case and may need a spare clip.
