Absolute horror story working with Dane Electrical - very bad product (NuTone) and customer service. We had a NuTone intercom system installed by Dane, which never worked from day one. Dane tried several times to repair the devices after the initial install, but they were never fixed. Dane blamed the manufacturer and the speakers, but the manufacturer didn't do anything to help. We even paid extra to upgrade the main unit to a newer unit, thinking that will solve the problem, but still the entire house intercom system does not work. Dane kept blaming our home as a "new build" which causes static over the intercom, so we had to pay extra to put in surge protectors, and this obviously did not help. Currently the entire system still does not work. Would not recommend Dane Electrical or NuTone devices.
