1st day, 10"-12"+ snow, hardly worked 25 min, thought about to return it. But fully recharged only 1.5 hrs. Took me 3 charges to finish the driveway with help of hand shovel..
2nd day, 4"-6" snow, worked much better/faster by combined with hand shovel and worked about an hour still 2 lights in batteries.
3rd day, 2"-4" snow. easy work with this cordless shovel and hand shovel. Finished the driveway still have 3 lights of batteries.
Conclusion: It didn't worked for 2 feet snow bank with hardened ice, but you can break it down by hand shovel and clean up by Voltask.
Don't expect it work like a 2 stages snow blower. Understand what's it's limits and take all the advantages from it then you will have a much easy snow shoveling experience.
