One more brand that I've used a lot over the past year or so, is Caseology. They have stunning designs that are precision made, good materials and easy to push buttons. All things that are important in a case. Oh, and it keeps the phone safe for years to come too. Caseology actually offers a slew of different designs, materials, colors and other things.
However the Wavelength is one of my favorites. It's a two-tone design in terms of finish colors and material. Black and silver (or other colors) and a TPU inside shell with a hard outer polycarbonate bumper around the rest of the device. Then there's a nice circled "wavelength" design on the back for good looks, and makes it easier to hold and grip. Furthermore, they use a light satin finish over the entire case to prevent scratches, discoloration and other wear and tear. They're nice cases that you'd expect to cost a lot more.
