They are certainly no Colt. Or S&W. Or Dan Wesson. Or Ruger.
Even Taurus is a better revolver in my book, than the older Bulldog Pug I had.
Maybe the newer ones are of higher quality, but I had my Bulldog Pug apart a few times, and there were some aspects of the design that, when you look at it, you truly get the impression the gun was designed as a disposable gun, with a life expectancy in mind, and not a long one at that.
If the design hasn't changed, and I don't see that it has by their parts diagram, better fit and finish won't do much for longevity. I carried mine for a while and it made a great carry gun, but stopped after I had it apart and saw what it was all about inside. Lets just say loctite is the name of the game with this gun, and I wouldn't carry a new one or an old one without seriously loctiting some of the screws.
My main gripe is the relationship between the cylinder latch release screw, the cylinder release latch, and the ejector rod. The ejector rod rests against the head of the cylinder release screw, and over time the ejector rod peens the flathead screw slot shut on the cylinder release screw, and you can't take apart the gun. When reassembling the gun, if you screw the cylinder release screw too far into the cylinder release latch and close the cylinder, the cylinder release latch no longer releases the cylinder....then it becomes a NIGHTMARE to take back apart when you can't get the cylinder to release. Then you also have the possibility of problems with the screw backing out, and the gun failing to lock up when the cylinder is closed.
IMO, it is a cheap, shoddy shortcut of a design that gave up quality and longevity for ease of manufacture and less parts, that WILL fail eventually if the gun is shot regularly.

Rant about my Bulldog aside,
If the newer .40 model has changed that, I have heard the quality of CA revolvers has gone up, so I would not refuse to own it if it were a good buy.
