You will note that, in the case of Janis, he did not favor the Clearvue as far as fit and finish is concerned, but rather offered some very legitimate and believable criticisms. You can believe whomever you like but I tend to place more credence in what people say who offer honest criticisms as well as praise for the things they own and use. All anecdotal evidence is not created equal.
I am indeed being a little unfair to Clearvue based on the fact that what they are selling is not a dust collection system but rather a kit the performance of which depends to a large extent on the skill and care of the person who builds it. I would also say that people like the authors of the Wood article have a right and even obligation to point that out.
