Well so far Amazon has giving me 2 replacements.Because the 1st unit was damaged in shipping.2nd unit1 set of lights do not work,tried switching the bulbs around,but it's something electrical.Why start to repair it myself,when I have the option to send it back.Overall a disappointing situation.This is a bit priicy,one would expect a better quality unit.Its almost a better option to buy 2 of the solarmax unit,save some money and have 2 better units.Also,for the price of this fixture ya would think they could install some leds for nighttime viewing...I would advise to look at other fixtures..Ok,thanks to amazon,I received another unit.And maybe a 3rd time is the charm,but as of now I finally have a working fixture.In this case at the end of the day,it isn't what you pay for.Just cause it's higher priced,doesn't mean it's always better
