"Received a facotry new - DEFECTIVE low voltage disconnect. I was required to pay for return shipping because it was the facotry's fault, not Powerwerx and they said it would not be fair to them to have to pay for the factory's mistake. The replacement product turned on but was not within specifications. They sated that they had tested it before shipping. However, when I asked at which voltage it shut down, they could not answer. (It turns off way too early to be useful.) Had to pay for return shipping once again to receive a refund on the purchase, minus $15.30 "
