Has anybody purchased any of these cases? I'd really like to see what they look like on the matter black 7 or 7 plus. I'm curious how the general frosted cases (without color) look on the matte black. It seems like the ones with color (black, blue, etc) mask the design of the phone, but if the frosted white makes the matte black phone look too much lighter in color, then I guess black is probably the way to go. Also, I really hate having a lip on the front of the case - I like to feel the curve of the glass. Does anyone know if any of these cases have a lip? If you have any other ideas, I'm all ears! Thanks!
