I had to wait for nearly a month before it finally arrived (not sure whom to blame), so I had the opportunity to use my phone "with" and "without" this case. First, the case is not as "black" as I expected - it is light grey and you can see through it. It also felt quite oily and slippery out of the packaging, so you might want to wash it before putting it on the phone. Once on the phone, it fits the phone pretty well and looks quite neat. I have to say that I like the colour now.
I marginally prefer the grip on the phone without the case. With the case, however, I've sopped accidentally pressing the on/off button on the side. I'm pleased I bought it.
