Last year we had ice dams due to an unusually brutal winter in Michigan causing me to research snow removal techniques which led me to your website.. I had to pay to have the snow shoveled off the roof and for the price I was charged for this service I could have bought four avalanches. After this winters first big snowstorm we put your product to the test with complete satisfaction in less time then it takes to shovel my sidewalk. An amazingly useful tool for anyone living in a snow belt. Old man Winter has met his match.
