I've had an Otterbox Defender for every iPhone I've had (4, 5, 6, and now 6s Plus). The others were of course a little bulky (for the 4 and 5 mostly), but this is the slimmest case you can get. Totally different, in that, it is almost (if not exactly) as thin as the new iPhone 6.
My son hates the OtterBoxes and would never wear one and therefore has had several broken and costly replaced screens. When he saw this case on my phone (about two months before "his" upgrade was due), he gave me his upgrade just so he could have this case....and the "fire" color is what also caught his eye. Plus, he did not want an iPhone Plus sized phone, and I did.
So now I have the iPhone 6s Plus Otterbox and it is as thin as it can be and designed pretty much the same, but out of all OtterBoxes for iPhones, the iPhone 6 (regular sized; not plus), this is the slimmest and best case. Hands down! I think you will love it, and these are great prices at Wal-Mart also.
I've never left a review at Wal-Mart online, but I had to respectfully disagree with the reviewer who said this case was bulky. It is the LEAST bulky case they have ever made for iPhones. The 6/6s Plus cases are a little thicker (not nearly as thick as the 4 or 5, 5s, and 5c), but that's because the plus sized iPhone 6's are naturally thicker than the regular 6's.
Thanks for reading. Hope this helped. If you can get the fire color, and red is your favorite color, this is a standout. I'm looking for the fire color for the plus sizes.
