Unit was easy to assemble. Used on some left over snow, worker great had a pretty awesome throw distance. As I have other battery operated tools I figured the batteries do not last for a long time. So I ordered a secondary battery. Will work great for my small driveway. So, we finally got 12” of snow, not the greatest blower for heavy wet snow. But if you can work it you can clear it. It is unfortunate that it takes 4.5 hours to completely charge these batteries with equipped charger. Recommend getting the 5.1amp charger for faster charging.
