1st time use, was very impressed!!!
I chose the 16" mower for its small size, light weight, and mobility in tight spots. Very impressed how quiet this little "toy" mower runs...doesn't sound like a mower at all, more like a hair dryer. Early mowing will NOT wake up the neighbors. Though small and light, it is powerful enough to mow my 1000 sft front lawn, and 1600 sft backyard (mostly flat)with one battery charge on number 2 wheel height setting. On my 1st time use, I did not need to use my extra 2nd battery. Love the easy push button start. Light weight housing material feels somewhat inadequate (majority plastic), so durability in tough usage remains questionable; only time will tell. The lightweight benefits though allow easy operation (no need to be self propelled), convenient storage as it can be lifted (about 35 lbs)onto a shelf, and easy cornering in tight spots. Collection bag in the rear works great, easy to take off and put back on. Haven't tried mulching yet. Mower handle was easy to adjust and assemble, just tightening some screws and securing its camp locks. Not sure why front and back wheels are of different sizes...could be due to angle of cut for the blade. Security key can get lost easily, I use a loop string to attach it to the handle when not in use just in case. First time use a on dry evening (front and backyard all done under 1 hr), I am very satisfied with this cordless mower so far. Will update review in subsequent use.

I would by this product again
i purchased this product 2 month ago and used it about 8 times already. This product is awesome. I was very reluctant to buy a lawnmower that uses gas, and or with a cord. for similar reasons such as, I want to avoid the use of gas near my house and extention cord issues. The GMAX is awasome. My yard is 7000 sq feet and I only need 1.5 full battery to cut the whole yard. its very light weight and almost noise free. I am very happy with this product.

Great little mower!
I'm a 58 age woman and this mower is perfect for me. It came fully assembled and after charging the battery, it was ready to go. I've used it three times now and haven't needed any help from my husband. The only down side is the back lower flap gets in the way of backing up; it flips forward when you try to pull the mower back, so making turns or maneuvering it in any direction other than forward is awkward and frustrating. They really need to fix that design; I'm ready to take it off permanently, but not sure what the impact would be. It also doesn't like wet grass and during the winter even in Calif., the grass doesn't always dry out during the day. I still love this little lawn mower, though. I gave up on a gardener for my back yard because of my two dogs, who make it nearly impossible for anyone to enter. This little lawn mower allowed me to take control of my yard and keep the peace with my dogs. :)

My new battery-powered lawnmower.
I have a small yard that I Ike to mow weekly during the grass growing season. My new battery-powered Greenworks mower is the perfect match for this job. I can easily mow my lawn on half a charge, and the mower works beautifully. It's light weight and maneuverability is what I enjoy the most. This has been a great purchase for me.

Perfect for those who are small ...
This is so perfect for my older sister who happens to have a prosthetic leg, she is able to move the light weight mower around everywhere between tight spaces and on inclines! It make no noise she can hardly tell its running, No mess, no smells for the garage and no runs to the pump for gas! We are very happy with this mower it will mow front and back on1 charge.Theres nothing negative to say about it. It takes up half the amount of space as an traditional mower. She is very pleased with the purchase. Thank You!

Purrs like a kitten
I have only used her a few times, but she was easy to assemble, right out of the box. I can hardly tell if she is running because there is no noise. Very nice and it is just what a new lawn needed.

So far so good.....
I use this mower to augment my John Deere rider. It's great for small spaces and edging that my rider can't get too. It's really light, and folds easily. I keep it on a shelf on a metal shelving unit I have. I've never needed to swap out the battery to finish my yard.
