If you're going to clear a large and wide driveway ensure that you purchase a two-stage blower for the extra umph to move the snow where you want it. Also, if you are at the extreme of the driveway length described in the advertising, consider a second set of batteries--not cheap--or be prepared for clearing your drive in two sessions. In Virginia this winter, we have had a 6" and 4" delivery of snow in my area and the machine performed well in both instances. My criticisms include: the lag between releasing the drive control lever and the machines ability to stop forward or rearward momentum, the battery compartment lights---which indicate battery status---being covered in snow while you're clearing, and the tendency of the snow blower to ride up over compacted snow rather than digging into it. Do NOT use this product on gravel. But I cleared 85% of my drive and walkway in less than 90 minutes for what would have been an otherwise six hour plus job. Overall, I think that this is a great product and in at least a dry powdery snow delivers about 40' (not 50' in my experience) on the turbo setting. Battery recharge was about 90". Just pay attention to the angle you place on the adjustable chute AND wind speed and direction---or your significant other will be calling you "Frosty" and the kids will try sticking a carrot in your nose.
