Review: 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.
Review: 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!

### ⭐⭐⭐⭐⭐ I love this mower!
*by A***S on May 15, 2026*

This is a great little mower! I have a bumpy hill in my back yard with a decently steep slope and it’s 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. It’s 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. It’s 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 don’t 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 it’s good to go again. I never write reviews but felt it necessary for this. I’ve used it a good 10 times already this season and hope it will continue to last without issue.
