initially bad battery charger, currently mower in for repair
initially this was delivered with a bad charger, support rma'd a new charger within a week. after batteries were charged was able to run a couple of hours before it jammed in heavy grass and would not restart. batteries are ok but won't run, contacted support and currently at local shop for warranty repair. so far not a fan based on reliability. support agents good at isolating trouble but long wait on hold before reaching them, limited hours on weekends. ordered this in feb 2016. I have been satisfied with other greenworks products but this one needs more work to before recommending. Design has some good features like easy cutting height adjustment, quiet and lightweight. Safety lockout start button is convenient.

12 weeks for repair :(
Only worked for a month before it started beeping instead of cutting. Brought it to designated repair facility and was told it would take 12 weeks to repair. So much for summer, now I have to purchase another mower! :(

Great Quiet Mower
I've had the 80-v Greenworks mulching mower since Mar '16. I used to have a corded mower but now I go wherever I want and mowing my .9ac lot is much faster. I've had people walk up to me and ask how can something so quiet work? even my dog doesn't move out of the way when I'm coming since its so quiet!
I need two batteries to mow the whole thing, but it works great. I've also purchased the blower and trimmer. Blower uses up bat power faster but has plenty of CFM.
I wish all my neighbors and lawn services used all elec equip!

Exactly as advertised
Found this mower to be exactly as advertised. I've a small lawn - battery was able to cut it twice before a recharge. First cut on new sod - very high grass - was easy. Did not get the self propelled model and did not need it but I do not have hills. I would recommend this mower without reservation. if you gave a big yard I'd consider a second battery and the self propelled option.

80V power is worth it
I switched to an electric lawnmower 3 years ago due to being tired of the pull cord and noise of gas lawnmowers. It was only 36V (not this brand) and power was barely adequate. Often had to go back and forth over the grass. Its expensive battery died so I decided to try a 80V mower. Great decision. Power similar to gas. Much better cut and speed of cutting vs the old mower. Only used twice so far. I am concerned about future reliability due to some other reviews. Also, the original charger did not function properly. Greenworks promptly mailed out a replacement.
