Mine never worked, they tried to give me the run around. Ironically I just googled it again because I was looking to make a makeshift one using a different panel and I found a bunch of threads with people in the same boat. Either their units are defective or they know they don’t work and are placebos for people. I’ve had to turn off all my motion alerts to keep the thing lasting longer than a month. Even with the solar panel getting a good 5 hours of sun.
