So far so good
I have only used it once so far- was very easy to assemble - and very easy to operate.

10,000 square foot usage - Not Close
Our total yard is 1,800 and we cannot cut the front and back on the same day because the battery does not hold charge long enough to complete either.

I cannot cut the back not the front fully without not having to recharge just to finish the task.

I am a retired woman. This mower is light. It was not difficult to assemble. It is very easy to use. I have been using it for a month and love it. It is perfect for small yards.

It works!
This mower was so light that I thought that it might be like a toy. But it really works fine. Also, I had no trouble with the settings for the height, as some other buyers report.

Very Convenient
This product is great for small lawns! I bought this mower because I have only have a front lawn which is small to midsize! Why spend lots on money on a mower and your lawn is not big? If I had a front and back lawn my decision would be to buy a bigger mower! I have used gas mowers for years but switched to cordless because of the need of not having to buy gas every time you want to cut your lawn! The downside is that you have to charge the mower after each use! Otherwise it's a great low price product!

Light weight and impressive.
Had this for a week assembled very fast and was already partially charged which meant I was able to try it out right away. It is very quite also I have tinnitus in my ears so it is a pleasure to use.

Reasons to purchase cordless electric mower
This mower is ideal because it is lightweight, quiet, Eady to start and takes little storage space. I am well be satisfied with this purchase and will help save the cost of hiring lawn care this year.

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!

Is battery removable for charging?
A shopper on May 14, 2018
BEST ANSWER: No, the battery is an internal battery that is not removed when it is being charged.
