seidio - top notch
The case fits very well and does not make my Samsung s6 feel bulky at all. My only criticism is that I could only get black.
My previous phone was an HTC one and I occidentally dropped it 3 times over time and the seidio case always protected it from any damage. I'm hoping I don't have to test my Samsung case but I'm sure if I do it will do it's job.
