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 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 3 out of 5 by Expected better from Otterbox My actual rating is a 2.5. This is the third phone I've had on which I've used an Otterbox case - I also use one on my Kindle Fire (that case is fantastic) and I've never had any problems with the previous two. As for this defender, I'm on my second one for my current phone, which I've had a year. I'm so fed up with it. Same complaints as others - droopy stretched out silicone, broken hard shell tabs and the built in screen constantly gets dirty on the inside. How is it protecting my screen when bits of dirt and dust are getting between the screen and screen protector? I read on one of the other reviews about boiling the silicone to get it back in shape - well that's a great idea and I will try that for sure, but it's ridiculous that I paid this much money for what should be a 5-star phone case from a usually great company and now I have to boil it in order for it to work properly. Really Otterbox? The good news is that it does protect my phone well (except the screen protector issue), as I have dropped it many times (even in a shallow mud puddle!) and have had no problems. The other good news is that when I replaced the first defender, I had a fantastic customer service experience. I am going to give Otterbox one more chance, only because I have had a great experience with three other device cases and I'm going to try another model. April 18, 2014
Rated 5 out of 5 by Great Case I have had my Galaxy SIII Defender case for 12 months now. It is great. It has protected my phone several times from falls of 3 to 4 feet. Because of my own clumsiness, I broke the holster after 1 month. Bought another and haven't had any problems with the holster since. After 11 months the outer rubber case was stretching out. Contacted Customer Service and they replaced it for free. I have recommended this case to others with the SIII, and the Otter Box Defender Series to friends that have the Galaxy S4 and I Phones.

Rated 4 out of 5 by Great case just one flaw First bought the case with my phone. Then the silicon started to stretch away from the phone. And the plug for the power jack broke off and other areas started to tear with in the warranty. Otter box replaced the case for me which was great. But the something is happening to the second one. April 11, 2014
Rated 3 out of 5 by so so I received this as a gift. It is big and bulky. The outer layer is pulling away at the bottom from trying to pull it out of my pocket when it can't be in my purse. April 4, 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.
