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.

Great investment and fun to use!
I feel I made a great investment in buying this mower! I have a small yard that I was paying for mowing service Rey month. No more. I am happy at how light and easy it is to handle this mower yet it is a workhorse! Battery needs charged until the light on the plug is green as well as all 4 bars light up. Handled my yard in 25-30 minutes and cleaned very easily. The grass under the deck looked like hay silage and that was nice because it was easier to clean up. Worth every penny! Cut was even and clean. Size is tiny but don’t let it fool you, it works hard!

Amazing!
This adorable little mower is amazing. I purchased this incredibly light mower for my front yard which is at the top of a hill. It's too difficult for me to get my full size mower there. I carry this with one hand! It plowed through 4 to 6 ' high grass with ease. Very impressive and not too noisy. Connecting to the charger can be finicky. I thought the charger was defective because although the charger light was on, the charge level remained at one bar for several hours. I took the battery out and tried again this time pushing the little blue bar in while connecting to the charger. That did the trick. Mowed my entire yard and only used one bar. I am thrilled with my purchase . It's fun to use and the perfect solution for those suffering from back pain.

Short Cuts for Grassy Lawns
Make sure to read the instructions completely before using, especially about the battery and preserving its life. The little mower is great for small areas. I loved the height adjustment and the ease of use. I am a senior citizen on a very fixed income so I wanted a way to save on lawn care between those larger project days. The mower maneuvers easily and I am able to handle the edges and the overall lawn. The mower performed as stated in the description and charging the battery is very simple. I highly recommend this item for someone looking for simple and handy.

I love this little lawn mower!
This little lawnmower is awesome for small, tight spaces. It's so lightweight and easy to push. I am a senior citizen and recommend it for those, like me, who don't want to depend on others. A weed eater is just too heavy, so I was happy to find something to cut grass that has wheels. I will say that it seems a bit flimsy, so not sure how long it will last. I've only used it once.

So Glad I Bought This Mower!
The mower was easy to assemble with plenty of power in the battery for me to start using the mower immediately. I bought the mower as an easy way to mow the 45-degree slope in my back yard. It works great! My arm and shoulder didn't get tired as it does when I use a string trimmer.

Battery stopped working after 1 year
Pretty lightweight which is nice, but I tried to use this for it's second summer season recently, and the battery won't charge at all. The charger indicates that the battery is fully charged when the battery is flashing red (low battery).

Fit My Small Yard
This small cordless lawn mower is great for tiny yards. I use it for my front lawn, which is about 50 square meters. It works very well. The blade spins fast and cuts the grass into small pieces. The grass looks neat and clean after mowing. I like the handle too. It’s comfortable and easy to hold. I can use one hand to finish the job. When I’m done, I fold it and put it in the garage. It doesn’t take much space. It’s small but powerful. Perfect for small yards!

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 it Edit: 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.
