Lightweight (1)
I am so happy that I purchased this lawn mower.
I am a 61-year-old female that truly enjoys cutting my large lawn with the ease of using my new lawn mower. I especially enjoy the fact that it is very lightweight for me to use. I find it extremely easy to push and steer. I am really pleased with the wonderful quality of the mower. I now actually find it enjoyable to cut my lawn on a routine weekly basis. I also appreciate the adjustable cut-lengths. My lawn appears very healthy. I am so grateful that I purchased this mower. I would highly recommend it. Thank you so very much for your great products! I also purchased the available discharge accessory for my mower and it works so well.

Great lawn mower - very easy to use
I just purchased this after having used a Snow joe snow blower the last 2 winters. So far I have used it twice and it works great. It could easily mow my front and back yards on a single battery. I like that it is very easy to adjust the height, and that I can keep the grass pretty long, 3", as I'm trying to fill in a bunch of bare spots this spring and it doesn't disturb my seeds.

Incredibly easy to use, and my 3 year old can easily "help me" push the lawn mower as there is a bar in the middle he can push. Just like with my snow blower, it is great not having to deal with gas and maintenance.

So quiet...neighbors can't hear a thing!
We absolutely love our Sun Joe mower! It is so quiet, cuts amazingly well, and is very lightweight and easy to handle. The many and easy to use adjust lengths are a huge plus to this mower as well! We would recommend this product to any and everyone who has a lawn to mow.

Great mower
This is a great lawnmower. Although 99.9% of all mowing is done on a regularly cut lawn, when I had to use it on overgrown grass - over 6" it cut right through all of it without a problem and did not bog down.

Just what I expected from this company
I looked at this mower because I already know this company. I have an 18 inch corded sno joe. A sweet little workhorse that plows through 15 inches of western NY snow on my 80 ft driveway for the past 4-5 seasons. Been using a corded mower for the last 10yrs. It has served me well but, that cord is getting as old as I am and God I hate gas powered tools with a passion. This machine is a simple to assemble and use as they come. The hardest part was waiting for the battery to charge(not bad though just a couple of hours. Even though the deck is narrower 16 vs 20 inches, I still manage to get my yard mowed in about half the time not having to constantly mess with a 100ft cord. Though my yard is fairly small the grass is crazy thick and this little guy seemed to handle it just fine.Nice and light, maneuvers well and gets into those tight nooks. Cuts nice and even and the deck has a nice range of adjustment. Really the only fault I can find is the grass bag is small and instead of emptying it once or twice, I have to empty it 3-4 times but, I can live with it
