Every manufacturer makes a bad one from time to time. Your chances of getting another bad one from them are the same as your chances of getting a bad one from someone else.

Did anyone else read the Tom Lieb (Scat Crank) interview in Engine Builder where he talks about harmonic dampers and totally comes down on fluid dampers in general? He also has other things to say about dampers, it'd be interesting reading for some of you.
