I haven't really put mine through any "serious" usage yet. Next time I go out to shoot (this weekend) I'll drop down into the woods and beat it up. The action sucked when I first got it, but after breaking it in it's nice and smooth, and locks very firmly. It's also sharp as hell and after some repeated slicing and sawing it hasn't lost a bit of edge. To be fair, it is a small-ish folding carry knife, it's not thick, so I doubt it will resist bending very well, but we'll see.
If it stands up to me beating it up I'd highly recommend buying one since they are only like $10-$15. For a cheap knife it has done surprisingly well so far.
