Review: Perfect Compact Mower for Small Yards and Obstacles - Don't be deceived by the small size, this mower can do big things! I bought this because I have a small yard with a lot of challenging landscaping obstacles (previous owner threw river rock pebbles all over the yard without putting anything underneath them and then called it a day.) It's perfect for what I need. Yes, there are times that I have to go back and forth a few times to cut down stubborn weed stalks, but it really is akin to vacuuming. It's super lightweight and compact, and very easy to start. It's about as loud as a weed whacker, so quieter than your usual lawn mower. It's plastic, but it seems pretty durable. I have the blades set high enough that the river rocks aren't a problem, and when I accidentally nicked a root it stopped, but started up right away with no issues after I moved to a different section of the yard. The battery seems to hold its charge pretty well, and the blades seem good for regular grass. I do have a lot of tough, fibrous weeds so the blades might need sharpening sooner than later. I like that it has three levels of cutting, the lowest level was like a buzz cut for the yard, much too short for what I wanted, but the 3rd height is perfect. I bought it on sale but honestly the regular price seems to be a good value. I'll update my review if anything changes over the summer, but I'm very pleased with this purchase.
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.

### ⭐⭐⭐⭐⭐ Amazing mower for small yards!!!
*by S***A on June 13, 2026*

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 wasn’t 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 won’t take up much room at all to store!
