Very intuitive and fast to put together. The 4Ah battery is plentiful. Sturdy metal deck. The automatic variable speed may save some power but lower the vacuum capacity when mowing light grass and passing over flimsy sticks without picking it up. All wheels height controlled with a single lever but it goes from 1” to 2” without fractions. When on 1” it is difficult to push.
I have used this mower twice since receiving it. The first cut was at its highest setting as my yard had gotten completely out of control with weeds almost a foot tall. It was so smooth and powered through all of those weeds without any problem. The simplicity of start and stop compared to typical gas made bagging and emptying the bag so easy. It was the fastest I have ever cut the lawn. A week or so later I went back to do a proper cut on my zoysia lawn. I set the mower at 4 height and went to work. My lawn is very thick in some places and you could hear the mower power up to get through those areas. Again smooth cut and easy bagging process. With the thickness of the grass, I was actually worried the battery would die before I finish. My yard is very steep and I was using the self-propel feature a lot. It had no problem and the lawn looked great. The easy adjust height made it easy to cut the edge without scalping it like often happened with my previous mower. Delivery is not the fastest, so be patient - it is worth the wait!
Overall the mower works very well. It's so nice to finally be able to cut the grass in relatively peace and quiet. Im very impressed with the battery charge and I'm easily able to cut my 1/3 acre lot size with plenty of charge remaining. I don't use the sell propelled though as the mower is easy to push. The self regulating variable power is nice and I have yet to even come close to stalling. I use the rear bag and it works very well and is super easy to removed empty. I would have rated 5 star but there is one minor flaw that I need to modify - the battery cover hinge mechanism is poor and doesn't allow the cover to fully open, making removing the battery awkward, I ended up disassembling the top cover parts and added a different huge so now the cover opens completely. It took about an hour and a half to modify. To me this is imperative as the cover is opened up pretty much every time you use the mower. Other than the poor battery hatch, the ergonomics are very good.
