Not had a Spigen product before but did my research (a bit OCD at times) and finally decided to go for this case, mainly on looks.
Was unsure about which colour would suit the Black Mist S4 as well...but decided on the Metal Slate and I have to say, it looks amazing...colour suits the phone brilliantly and even enhances the look and feel of it.
The phone fits perfectly into the case, doesn't move around at all and also provides a lot more grip to what was a very slippery phone before!
All the port cutouts are perfect and I have tried every charger and headphone jack I have lying around!!
The case itself feels a lot sturdier than I was expecting and I'm sure if dropped would actually stand a good chance against breakages! The small lip around the front of the screen is also more than I expected and can be placed face down no problem. Highly recommend this case for the S4 and if you're unsure about colours...the Metal Slate on Black Mist looks really smart and sophisticated in my opinion.
Very impressed and would highly recommend especially if you're looking for something that hardly adds any bulk to the phone, but still provides the necessary protection...plus looks amazing!
Any questions, feel free to ask.
Overall though...nice job Spigen!
