Finally found a lawn mower that's easy to assemble - about 5 to 10 minutes! No need to worry about gas or oil or problems with starting up your lawn mower! This little mower is lightweight, lighter than my vacuum and easier to handle! Also have an electric with cord Sun Joe MJ403E, but I wanted a CORDLESS one! The grass bag holds 6 gallons, a lot more than it looks like. Warranty: 2 years. My next lawn mower WILL be a Sun Joe!

Love the Sun Joe MJ401C!!!!!
Living in a downtown home in Indy, it's absolutely perfect for my postage stamp sized yard.
Cuts well, the charge lasts long enough for me to cut my neighbor's yard too. I haven't used the bag yet as I like to mulch the clippings into my yard.
Extremely light weight but does a fine job.

My only recommendation would be to add another slot to raise the rear wheels as the highest setting is still TOO short for hot and dry summer weather. I'm sure this could be an easy design change.
Other than that, I LOVE IT!

Don’t buy this mower!!
Easy to use mower. Bought the mower in June and I have used it every week. The issue is it takes forever to charge then it dies in 15 minutes and you need to wait another 4hrs for it to charge. Mower bogs down and turns off if your grass is too long. I have to mow my yard with the front wheels popped up in the air. Then I have to go back over it for second time. Even then it bogs down and shuts off. Essentially, I have to mow my yard 2-3 times over two days to get it right. Otherwise, the grass is uneven and looks horrible. I mow my yard once a week and this mower can’t handle the growth. Going to go get a new mower ASAP. I’ll probably go back to a Kobalt.

Much quieter than my gas mower. Much lighter and easier to maneuver in tight spots, Charge last for at least 4 cuts! Get one. You'll thank me later.

Great little mower
Light, lasts about 45 minutes per 3 hours charge. Saves me money-I don’t need a landscaper, and free exercise to boot! I just wish I didn’t need to be ocd about needing to unplug it right away after a 3 hour charge. I mow about an half acre in 2-3 charges, depending on grass height

Perfect lawnmower for me!
The shipping was fast! Lawnmower works great and it’s light and easy to push. For me, it’s perfect. I was surprised how good a job it does for it’s size.

Incredibly efficient and "precious"
Love, love my Sun Joe cordless. I live in the country and have to get on the tractor for my 3 acres. This little guy is a whiz around and under trees where a large machine cannot go. Also use it for my smaller, backyard dog enclosures. Sun Joe is so light that this senior female can push it with one hand. Fully charged it gives me 45 minutes of effortless mowing. Easy to set up. So light weight.

It is also too cute (perhaps not of interest to the gentlemen), but it reminds me of R2D2. Who would think mowing could be fun in the hot Mississippi summer?
