I doubt they ever ship a working unit. I smell a scam. Nothing I saw adds up to a realistic product at the price they are claiming. The unit is too light, It claimed to use 60 watts/1 amp, which at 12 volts DC is 5 Amps if my calculations are correct. walls are too thin, solar panels are too small, not enough room for a battery that will power it for 8 hours. Even if they could get the tech to work, they would need to produce thousands of them to get to an affordable price point. The biggest clue to it being a scam is the $ 1000 original goal. That low of a goal would not give them the capital to produce it.
