I got the Spigen Slim Armor in black and i think it's an excellent case.
A couple things I noticed are the power/volume buttons are a little hard to press (like others have reported), but that appears to be becoming easier as the case is "broken in" so to speak. The more I exercise and use the buttons, they are becoming easier to press.
The only other thing is the gloss black hard plastic shell doesn't sit perfectly flush with the TPU inner layer. What I mean by this is I run my finger from the top of the case on the TPU layer, down towards the bottom and when my finger transitions to the gloss black plastic layer I can feel a very slight raised edge. Meaning the hard plastic layer is very slightly sticking up higher than the TPU layer. It's very minimal and isn't a big deal at all. I also notice the same on the bottom seam, although it isn't as pronounced as on the top seam.
Curious what others cases are like? Does anyone else feel this slight raised edge feel, or is it perfectly smooth/flush?
Note the seam fits perfectly, no gaps between the 2 pieces whatsover. I'm only talking about the hard plastic layer sticking out a hair past the TPU layer.
