I have the Ringke Fusion and like it. I had it with my N4 as well and never had any issues. Plus it shows off the sexy back of the phone.

I posted this in another thread, but I bought the Spigen Ultra Hybrid Case as well as the Ringke Fusion.

I've gotten the Spigen and I love it, the screen protector that comes with it is a great screen protector as well. I'm getting the Ringke Fusion on Wednesday, and Wednesday night I'm putting up a comparative review video on Youtube. Those are two very popular but similar cases. You can check out my video when I put it up tomorrow night.
