This has been a great investment.  Having a lot of snow this summer, it did a great job keeping the driveway clear.  Even with 6"+ of snow the length of my driveway (about 100'), it had no problem clearing the driveway.  The multiple speeds are convenient having different depths of snow.  Faster speeds make the lighter snows go a lot faster and slower speeds help control the blower with thicker snow falls.  Overall I am very pleased with this piece of equipment.  The only negative I have is the tires could have deeper tread.  I will need to buy chains to stop the slipping.
