Chuck, not at all, at least in my case I have 3 power bars if one breaks I still have the other two that I can easily transfer vital plugs programing into any of the other bars, all bars are capable of reading ph-temperature-level-orp etc etc etc so in case of emergency you can disconnect the USB probes and just relocated them into any of the other power bats, I guess my point is that with this unit your chances of being out of a controller are less likely
