OK it arrived and I trimmed and installed it! But my first thought about it is it feels slick,the buttons are harder to press, and it's hard to see what button is what if your not able to shoot by feel alone. It does look good, and I'm sure it will offer quite a bit of protection against bumps and scrapes! It doesn't fit as tight on my D90 as I would have hoped, so grit could get in and I doubt it would help much for moisture at all. But on the other hand it would be easy to take off to clean out any grit. It is a bit harder to install lenses on my D90 with the case on, but that may not be an issue if care is used to make sure the lens is installed correctly.
I would think ruffing up the surface would solve the slick feeling, but the case does make the camera feel bigger and that could be either good or bad depending on your hand size. In my case it's bad, though the slick feel might be making it worse than it actually is.
I will try the case for a while before I decide rather to take it back off or to leave it on! I'm not sure I like it much, but I'm trying to reserve judgment to give it a fair chance despite my issues with it!
