We've had Dual Drive set-ups on two of our Bike Fridays for over two years with minimal problems. One time last year wife's click box wouldn't allow her to shift out of low range when we were 5-6 miles up the coast. I couldn't get the click box off, either, but she was able to ride home with the nine gears she did have.
Applied some WD-40 when we got home and I was able to get to come off and operate properly, to boot. Secret seems to be removing the click box and re-installing it once every few months.
In my opinion, it's biggest drawback is probably the weight it adds to the rear of the bike.
