All around solid lawn mower
I purchased a 21 inch cordless brushless lawn mower with 4Ah 80 volt battery in April 2020. My lawn is flat so I opted for the non-self-propelled model to save on battery life with the hopes of getting my 0.30 acre lawn cut on a single full charge. I have now cut my lawn four times, three of the times making it through the entire cutting on a single charge. The one time I did not was likely due to the sensor that increases the blade speed when running over thick grass areas, which happened on several occasions on that one cut that I did not make it through. Overall, I am very pleased thus far with the cutting quality, ease of pushing, and battery life.

Have used the machine twice, since purchase, first time in tall grass, worked great in tall grass and is great in keeping grass trimmed now.

quiet , easy start, lightweight
I am very pleased with this product after just one use. The battery charged in under an hour. Height adjustment is very simple and easy to do. Starting involves the push of a more cord pulling. The speed adjustment of the blade takes a little getting used to. Some grass clippings are left on the lawn in thicker areas. I have 3/4 of an acre, and battery easily lasted as long as I needed.

Puts the thrill into mowing
No noise. No vibration. No exhaust. Just now. The models are changing so rapidly now. More choices. More variations. My 80v model already has different wheel sizes. Different paint/color scheme. Even got a new lawn service so my grass would be thicker, greener and faster I could mow more often!

From the minute I opened the shipping container, I was impressed by the fit and finish of the machine and was more impressed by the ease of getting it set up and operating. I use it for my front yard and trim around the rest of the property. All that we use it to do gets done on one charge of the battery, and the longer we use it the more we like it. It is quiet and therefor we can use it latter in the day after work, which for me is around ten pm. I have already told my neighbors and family members about it. Very Very Good Investment in green equipment. Buy it!

Easy To Use
Lack of Power
Easy to use but I have to mow every few days
I love the ease of use and the battery has held up its power (7 months now), but I think the blade is very dull. It seems like my yard is not getting cut but more matted down. I'm not collecting as much grass clippings as I think I would using a gas powered lawn mower. Additionally, if the grass is even slightly damp, it sticks to the under carriage and I have to stop the mower every 2 strips to clean it out. Here in NC, with all the humidity, seems like the grass is never fully dry.

Power and Run Time
I've owned many battery powered mowers, most major brands and competitors, over the years and this is hands down the finest. Great combination of all desired qualities. It's relatively new so time will be the ultimate judge. .
