I purchased this case in the store because I wanted to physically feel it before getting it.
This is the only case I could find that had any sort of "grip" to it. All the other cases were too slick and I was afraid the phone would slip and drop, especially if I was trying to hold the phone with one hand (since I have the iPhone 7 Plus and it's nearly the size of an iPad mini).
While this case does have a smooth surface, it's made out of that flexible, rubbery (or whatever) material that your fingers sort of "stick" to (which is a GOOD thing), yet it doesn't show finger prints and it still allows the phone to slip in and out of pockets easily.
I like the minimal design because it stays true to the iPhone "look" (I got the black case for my black phone) without adding a ton of bulk.
As far as the protection factor, I haven't dropped my phone yet so I can't really give an informed opinion on protection, but I'm hoping it protects well (fingers crossed).
The only complaint I have is that this case makes the power button on the side EXTREMELY difficult to activate, so it requires you to push REALLY hard to get it to work.
Overall, I'm pretty satisfied with this case and I'd recommend it, but I do wish the power button functionality worked a little better.
