Second one works so far
I've tried both types of batteries that it claims to auto charge. Multiple manufacture types. I've unplugged it, moved it, waited over night, etc. All it does it light up completely green.  UPDATE: I asked for a replacement. It came in one day. It seems to work as advertised. I bumped up to three stars because they replaced it, so that is good customer service so fast. If it continues to work for 6 months I will go up to 5 stars because if something works, it works.
Rating: 3 stars
