I purchased four LOR Easy Light Linker a year ago last July for our 2018 Christmas display, during testing this year (2019) one ELL failed. I open trouble ticket and LOR was very responsive and sent replacement, about two weeks into to 2019 Christmas Show the second ELL failed. Now I'm starting to worry so I again open trouble ticket and with some discussion LOR did send me another replacement. Now that I've had a fifty percent failure rate of ELL's I'm worried and I'm looking for alternative solutions to ELL's. Anyone have suggestions?
