THE FIRST TIME MY HUSBAND USED THIS, THE BELT SLIPPED OFF. HE DID NOT REALIZE THAT WAS THE PROBLEM UNTILTHE SNOW THROWER HAD COOLED DOWN AND HE COULD TAKE A LOOK AT IT. SINCE IT IS PLASTIC, IT DOES NOT TAKE A GREAT DEAL OF USE. WE TRIED SWEEPING OUR DRIVEWAY WITH IT, WHICH IS 2 CARS WIDE AND A LITTLE MORE THAN A CAR LENGTH LONG AND IT OVERHEATED SO BADLY THAT HE BELIEVES IT WILL NO LONGER WORK. IF IT HAD A GUARANTEE, WE'D SEND IT BACK. I THOUGHT I HAD ORDERED A NEW ONE BUT HE TELLS ME IT WAS RECONDITONED AND WE HAVE NO RECOURSE. NEEDLESS TO SAY, WE ARE VERY UNHAPPY WITH THIS PRODUCT.
