For what it’s worth, in addition to three GW-180’s, I have also been using three Z-1000’s for over 14 years. Two of the Z-1000’s are used for accessories, and one for running engines. No problem with the controller for the engines, but one controller for accessories, which doesn’t get used much, seems to “corrode” inside. Lights flicker as you move the handle. I take the top off, spray with tuner cleaner, and it works fine again. I have found the circuit breaker sufficient for protecting the electronic circuits in my engines. Also, the finish on the controller can be scratched off. Z-1000 is good, GW-180 is better.
