I accidentally sent 2 Phix batteries in original boxes with chargers back to get replaced. The initial SNAFU was on me...when I ordered the Phix starter kits ET was sold out so ordered from Phix. Because I had done so much business with ET it slipped my mind that I had to order somewhere else. I emailed ET about the mix up they finally did respond and assured me they would send my product back so I could return to place of purchase. When I received the product ET had only sent the Phix batteries, not the boxes or the chargers. I will not be able to fill the warranty criteria without original boxes and chargers. The honest way to have handled the situation would have been to return all products that I sent to ET. BEYOND DISAPPOINTED!!!!
