For clarification, Tagan is no longer being recommended because of their attitude toward negative reviews.
This [H]ard|OCP review is one they got snippy over. Instead of attempting to rectify it, a company representative had a fit, and the company didn't appear to correct him.
The impression is that Tagan (the builder of this ABS PSU) isn't concerned with a quality product. A company that cops that sort of attitude will not be recommended because it's appears they're more concerned with looking good than providing a quality product.
