For a homeowner this is the perfect machine. I like to cut my lawn before work so it's really early and since it's quiet no one knows I am out there cutting. I have a large lot at 3 acres (not all grass. It's been a great machine!

Have to learn this mower's agenda
Two batteries don't do the job - IF I TRY TO CUT THE GRASS TOO SHORT. However, if I move the setting a bit higher, the mower doesn't strain and the batteries work just fine. In other words, don't make the batteries work too hard!

Battery life
As the others have stated, the mower itself does a great job, easy to push and adjust, quiet, however, the battery life is not as described. I have a small yard and have not been able to completely mow it entirely at one time Using both batteries. The batteries are too hot to start the recharge immediately and then takes more than two hours to fully charge.
I am retired and did not expect to spend all day mowing my lawn!

Battery life is a problem
This mower cuts well and does so quietly. The adjustable settings are quickly and easily changed to suit need; however, battery life is not as advertised. My yard is probably a little less than a 1/4 acre then remove the area of the decks, and gardens from that. Took two fully charged batteries this afternoon to cut my front and side yard. Put one of the batteries on to charge which took approx. 4 hours. Then started cutting the back yard, and only got about half of that done before the recharged battery quit. Will have to wait until tomorrow to finish off the remaining yard.

lawnmower good...battery bad
I am quite happy with the lawnmower itself it is quiet, cuts cleanly and easy to handle. Unfortunately the battery doesn't meet the same standard, on a full charge will last perhaps at best 1/2 hour and then will take up to 2 hours to charge, so even the benefit of 2 batteries is kind of wasted.
