Freezergeezer, I have a couple of the Rough Riders, a muskrat and a barlow. Both are pretty good and good looking knives. Both also have little quirks. On the muskrat, one blade has a softer backspring that the other. Both blades are quite sharp out of the box. On the barlow, the nail nick on the smaller blade sits just below the frame line so you have to sort of slip your fingernail down and into the nick to get the blade up. I have just under $10 per knife in mine and half that was shipping. Based on them though I am currently considering a Rough Rider Loveless hunter copy with rootwood handle. Just something to tide me over until I can get a better knife in the same pattern. I love the look of that pattern.
One thing I've found in Chinese mades in general is that they are a bit heavier that say a comparable Case or Boker. I find I am quicker to carry one of my yellow handled Cases or one of my stag handled Bokers (a whittler and a congress) instead, even though I have the Rough Rider muskrat and the Steel Warrior Cooperhead (mentioned in next para.) in my rotation.
Probably the best of the Chinese knives out there that I've come across are the Steel Warriors. I only have one small copperhead, but it is very well done in the fit and finish department, and came nice and sharp. On one hand it was good to get a well made knife for $10 or $12 that compares very well against a Case in terms of quality. On the other it is sad to me for it makes it that much harder for the western knife companies to compete in the marketplace and old, respected firms are endangered. Three things the western companies have going for them though are that 1.) They still make knives in carbon steel that carry lighter in the pocket. You can't get that with a Chi-knife. 2.) You can call most western companies and actually talk to a person and deal with customer service issues. 3.) There is a heritage that comes with a Case, Boker, Camillus, Kissing Crane, Schatt & Morgan, etc., that while being intangible for the most part, is something that is a strong affinity in traditional knife lovers.
So to answer your orignial question, thay aren't bad, but can be found much cheaper.
