I voted satisfied.
I have fired all kinds of different ammo through it, and never had a glitch. I don't clean it meticulously either, although it has been cleaned a couple of times in the hundreds of rounds it has fired.
My only kvetch is that the matte finish is a rust magnet. After an outing at the range once, I just put it back in the safe leaving the dust/dirt/grime on it. A month later, I checked on my guns just to see what was up, and these smilies sum up my immediate reaction:

There was brown all over the receiver, down the barrel rib, all over the barrel, I thought it was over. But after a quick wipe down with those blue shop towels from Canadian Tire and a liberal application of gun oil, I have never seen this occur again. Now I make sure I wipe it down every time I get back from the range. In fact, today I bought a bottle of G96 since I heard that it is one of the better oils for protecting guns. We'll see how that goes.
After all is said and done though, it is a very functional shotgun and has given me hundreds of rounds of fun, and will continue to do so I'm sure. Although susceptible to rust, casual wiping will keep it in check, and does not detract from my enjoyment of the gun. Between the Mossberg and the Remmington in the same price category, the Remington was definitely the gun for me, but of course, YMMV.
