Great mower and easy to assemble and use out of the box.
Was able to put this together in about 5-minutes with no instructions. The battery already had a charge so I immediately took it out for a test run. After a minute or two it became apparent that it was cutting great and that I had the setting too low (level 1) but it worked really well, quickly. With that, I kept going in my small yard and then switched to level 3 before heading to the curbside/sidewalk area where it again worked great. Not having a bag to catch grass wasn't an issue since I have a lawn/leaf rake which only gave me about 2 handfuls of cuttings at the end. I missed one spot raking so maybe I'd have had 3 handfuls total.The majority of grass clippings end up under the housing above the blade, which explains the the little scoop included that attaches to the handle. Once finished cutting I had it upside down and scoop-cleaned into the compost bin-no water needed (nor should any be used) in about 5 minutes or less. Simple.It was really quiet compared to a traditional gas-powered mower and probably on par with an electric mower and possibly more quiet than some others.What I liked most is I could move it really easily as it's very lightweight. It stores really well in my small shed. Overall, this is a great unit meant for small spaces that's easy to put together and use. I hope it lasts a long while.In my picture, you can see a bit of a U-Shape in my small lawn (divided with a thin fence) and that's something I couldn't do with my push-reel mower as it was a bit too big and also because the ground was bumpy due to dogs having been in the yard previously. I'd have to constantly lift it and set it down when I hit a corner, etc. No more.I'll add more updates later but for now, I'm really please.

Amazing mower for small yards!!!
This thing is incredible!!! it works so well and makes mowing my relatively small backyard a breeze! Especially as a fairly sedentary, middle-age woman:). I did my whole backyard on just one charge of the battery, and this is lightweight, very, very easy to maneuver, even on some of the bumpy hilly rocky areas of my yard! And it cuts the grass perfectly! Not very loud either. I am so delighted with this purchase as our yard is really too small to invest in a giant, regular lawnmower, but cutting it with the Weedwhacker wasnโt working as well nor was it as easy as this mower! I highly recommend! Oh, and it was simple to put together too, and I love that it folds down so that it wonโt take up much room at all to store!

This little guy works great.
I'm almost 79 years old. To get to my very small back yard I have to go down two flights of steps. I was able to get my old electric mower down there but it was becoming more difficult. I can carry this little mower easily in one hand. The blade is only 9 inches wide so mowing is more like pushing a vacuum cleaner than a lawn mower. It clips the grass as short as I need it similar to my older electric mower. There are no clippings to empty or pick up, it mulches the grass down to very small bits and sends it back to the lawn. My front and back yard combined are less than one thousand square feet. The battery pack easily lasted long enough to do both. So far, I'm very pleased.

Great Purchase!!
Great little mini mower!! Easy to maneuver, even on sloping areas! Battery life better than expected too! Perfect for weeds between plants or small yards. Feels like Iโm vacuuming my yard. Easy!!

Battery power great, but plastic bagger letโs seeds and debris escape.
The, so-called, bagging attachment is plastic with vent holes, which is bad, because, unlike the bag material on mowers, it allows seeds from bad grass and weeds to escape. If I had realized that, before using it, I would have sent it back. Itโs a push mower as well, but light enough to not be too difficult to handle. I lIke that it is battery powered and a good price. I use my riding mower for most of my lawn but itโs not a bagger for leaves or bad grass and weed spots it canโt fit in small areas. I wish I had added a few dollars and gotten a self propelled one.

I love this mower!
This is a great little mower! I have a bumpy hill in my back yard with a decently steep slope and itโs such a pain to get my regular mower up there and maneuver it around. This thing does the trick, and saved me from hiring someone else to do it. Itโs lightweight - I can carry it with one hand if needed - and I find the battery life to be just fine. E.g., today I mowed for about 30 minutes and checked the battery when done and it showed there was still 3 out of 4 bars left. Itโs pretty quiet, especially for a mower. I find I use it more like a vacuum, pushing it back and forth rather than like a traditional mower, since the space I have is rather uneven and I donโt want to miss spots. Sometimes it stops if I hit a patch of very long/thick or wet grass and I just turn it over and scoop out the grass that clumped up and itโs good to go again. I never write reviews but felt it necessary for this. Iโve used it a good 10 times already this season and hope it will continue to last without issue.

Does a great job as my gas powered weed eater with half the effort!
I was hesitant about purchasing this mower but I'm glad I did. I let my grass get too tall because using my heavy gas powered weed eater is so hard on my back and knees. I was afraid the grass was too tall for this little mower to handle. But moving it back and forth like a vacuum cleaner it was able to get through it. It will do even better next time because I won't let the grass get so tall. It takes so much less effort to use due to its wheels supporting its weight and because its so light. I'm 71 years old and don't have a big yard to keep up with, so I think this will perfectly fill the bill! If you're on the fence, I'd say go for it! I think you'll be glad you did!

Mini Cordless Lawn Mower
Awesome little lawn cutter. Got it delivered today and in under 5 minutes had it up and running, went straight to front yard and cut my grass in under 5 minutes. Very easy to use and store. This is a nice little easy and efficient tool for small yardsโฆ..

Amazing, lightweight and powerful
Been looking for a battery powered lawn mower for a long time and Iโm glad I chose this. It was so easy to assemble and it works perfectly. So much easier than a gas powered mower.

Perfect for the older person with a small yard
This was purchased for my 77 year old mother who is quite frail, lives on her own, but has a small yard to look after. This mower is easy to assemble and use. It maneuvers like a vacuum cleaner and the battery is easy to remove and charge. The mower is very light weight and perfect for a small town house lawn. I highly recommend itEdit: the product stopped working after 8 weeks of semi regular use (used approx once every four days for less than an hour each time). The warranty is only one month after month after purchase. Luckily I contacted Amazon and was refunded.
