I bought myself two of them, and yes, I really like them. They're stout and sturdy, and they have a good feel in my hand -- but remember, they do feel "mini." That is to say, they don't fill the hand.
I have one gripe about them, and that is that there is some tiny bit of inward curve (I would hesitate to call it "recurve") on the edge near the handle, making that part difficult to sharpen on my chosen stone, which is a flat Spyderco Ceramic Whetstone. You need something like the rounded edge of a Spyderco Profile to handle that part. While the Profile used to be my sharpening system of choice, I don't favor using it now as much as before I got the Whetstone.
The Mini-Pit Bulls I have are now extremely sharp. I know that the steel (AUS-6) is not the "greatest" but I'm sure it's just fine for my purposes.
Since these knives are sold for under $30, I think they're just fine. The sheaths fit nice and tight, btw.
