I was apprehensive before installing this on my iPad. After all, the iPad is a ~400 dollar investment. Thankfully, this case actually comes with a little iPad "stand-in" that you can install in the case.
Why would you want to do that? Well, because with this iPad stand-in successfully installed in the case, you can then throw the case in a pool, bathtub, or other likely body of water an iPad might fall in to prove to yourself that it's waterproof.
I did. Left it at the bottom of the tub with a couple of weights holding it down, for an hour. After I recovered the case I pat-dried it with a towel and opened it up. The fake iPad inside was totally dry.
I then installed it on my iPad. Fit like a glove.
Now I know if this thing takes a quick spill somewhere it shouldn't, that I don't need to be too worried about it being ruined.
That's peace of mind right there (And it should be. This case ain't cheap).
