Ok, it's cheap and we all know what that gives you. but this is too much. Had a guy coming to fit it. took him 2 and a half hours! outside casing did not fit other side and he struggled a lot, so much so that he scratched the black plastic and ruined it. I mean, Peruvian was hired on task rabbit. a bit mistake! a real cowboy builder. Task rabbit even refunded me the whole enchilada. My experience with purchases coming from china is always bad. Light works though. sensor is extremely sensitive even after turning its sensitivity to its lowest. what can I say, maybe it wasn't my day.
