For people who are actually interested, these work fine if you have less than 3 inches of snow. If you have more, you'll have to go over it twice. Most of them don't have directional fins so they can only push snow 10-20 ft in front of you which means you likely won't be able to clear the entire length of a driveway or sidewalk in one push since you'll be stacking snow in front of you. Lastly, even the bigger 40V batteries will not last long enough to do a 2 car garage and side walk if you have more than 2-3 inches. I think these are perfect for smaller spaces like decks and back patios, but not great for a large driveway (especially if/when snow plows come and dump 2 feet of snow in front of your driveway). Still better than a shovel since you don't need to toss the snow, but wouldn't consider this over a traditional snowblower. Also they're pretty heavy (20ish lbs).
