Got my case today. First impressions, it's nice, the clear back allows me to admire the back of the N4 (which is the reason why I got it). It seems as thick as my Atmosphere case that I've been using.
Gripes:
Buttons--it's hard to tell if I'm pushing the button properly without looking at the phone. There's no response unlike the Atmosphere.
Likes:
The back, nice to be able to admire the back of the N4 which was one of the big features of the phone.
Hole alignment--it looks like all the holes align with the case
Button construction--unlike my Atmosphere, it seems the buttons are made of the same material as the sides, so less chance of it breaking off.
Minimal packaging.
Feet at the bottom of the case so the clear plastic doesn't touch a flat surface
Do note, there is a film on the bottom of the case (wasn't obvious to me)
I'll be taking the fusion for a spin for the next few days.
