WE PURCHASED THREE OF THE ROLL AND GO, ALL THREE WORKED FOR ABOUT 2 DAYS THEN QUIT WORKING, TRYING TO SEND THEM BACK IS A JOKE. I HAVE DECIDED THAT I NO LONGER WISH TO ORDER THE PRODUCTS FROM THEM. I HAVE A TOTAL OF NINE UNITS USED FOR HEATING MY HOME AND CABIN, OUT OF THE TEN ONLY TWO WORK. THE VERY FIRST UNIT WHICH I PURCHASED SEVERAL YEARS AGO IS THE ONLY ONE BESIDES A SMALL UNIT THAT WORKS. I AM VERY DISAPPOINTED IN MY FOLLOWING PURCHASES WITH THE COMPANY. I HAD CONSIDERED TRYING AGAIN BUT IT SEEMS LIKE IT WOULD BE A WASTE OF MY TIME AND MONEY. I THINK THE COMPANY SHOULD CONCENTRATE MORE ON BUILDING A BETTER PRODUCT VERSUS SENDING OUT REBATES FOR NEW EQUIPMENT BECAUSE EACH PRODUCT IS WORSE THAN THE LAST
