It's quiet, cuts regular grass great. As advertised, thick grass stalls the motor but my gas mower chokes on that stuff too. The handle angles up higher than my gas mower so I have to get used to maneuvering around differently but no problem. I hope it lasts for many years.
This mower is solidly built and has plenty of power. I like the 2-position adjustable handle. Storing the mower is a breeze. Just press the buttons on the handle and fold it over, then lift the mower on its end. It only needs about 2 feet of space to store it in a garage or shed. Four stars (but not a game-changer) because the built-in cooling fan in the battery charger is somewhat loud and the LED headlights on the mower stay on and can't be turned off (hoping the LEDs don't put a drain on the batteries). I own 3 other 60V Greenworks products (blower, string trimmer and hedge clippers) and very pleased with them, so I'm expecting the same good performance from this mower.
I love this electric lawn mower! It has plenty of power and convenient features like the headlights and easy to hold auto move handles. Highly recommended!
No regrets! The batteries charge fully in about 2 hours and I can cut my whole (relatively flat) yard (about 1/3 of an acre) in one battery. I can store it upright and it takes about as much space as 3 folding chairs. The bag can hold all of my lawn clippings from a single day.
