I bought the Otterbox Defender Series case for my HTC Rezound not too long ago, off of htcpedia.com for a somewhat discounted price. At the time I bought my phone I bought the Verizon 2750mAh extended battery as well, and the Defender seemed to be the only case I was really interested in getting that covered the bigger battery. So far, I've loved the protection, the durability, and the ease of changing between the regular battery and extended battery, as well as getting it on and off quickly.
My question in starting this post is, do you like it?
I find it quite bulky when inside pockets, and it's hard to get out once it's buried in there. It's huge, and God-awful looking some days in my opinion. But for the protection, I think it is definitely worth the money.
