i purchased a 48 volt chordless snow blower which failed after 10 minutes of running i was told to send the unit back which i did. after two weeks of waiting the replacement showed up. this replacement also ran for ten minutes then failed after many phone calls i was told to ship the batteries back for replacement i was never told to ship them in two different boxes. i recieved one battery NOT two the unit is totally useless without two batteries. i was told the second battery would show up after another week. nothing yet!!!!!!. the winter will soon be over and i feel i will be stuck with a snowblower that will be out of warrenty next winter
