Delivery was via FedEx, assembly was easy. Batteries charge to full in 90min on 3 separate circuits. Had some issues with error codes in the first few weeks, however customer service was responsive and quickly fixed the issue. Chalk it up to new technology/early adopter tax.
I have BOTH the 21" and the 25". I originally bought the 21" thinking that everything was good. I quickly found out that my yard is much larger than I had thought. SO, I recently bought the 25" and went from a 2 hour job to a hour and 15 min job. It saved me 45 min a week on the yard. Sometimes even TWICE a week because my grass in some areas loves to grow. If you are debating on this machine or another GET THIS ONE. It handles a lot and saves a ton of time because it is so wide!
This lawn mower replaced my aging 18 year old Craftsman gas lawn mower. As I would expect with other battery electric lawnmowers, it is quiet, lightweight, easy to use, and generally works well. There are only two things that I don't exactly like. The first is that "standard settings" don't cut my lawn well. You need to remove the high efficiency blade and you need to use the turbo button. This will drain the batteries quicker. Second, the self propulsion has a delay. When you squeeze the lever, it doesn't immediately go. Then when you let go of the lever, it doesn't immediately stop. This is not the end of the world, but it just takes some getting used to.
