    The first unit didn't run much more than 50 feet, but that exposed me to Sun Joe's excellent customer service. Within a couple days the replacement mower arrived, and I have used it all summer long. It performs flawlessly, and even bags long wet grass really well. I love how lightweight it is, and how easy it is to adjust the cutting height. My old gas mower used to almost completely wear me out from trying to start it - so I love that all I have to do is push a button, and compress the lever. It is a really well designed mower, and great attention to details is self evident.

    The lawn more is entirely made of plastic. Even the wheels are plastic. It makes it very light but not very sturdy. When the lawn bag is almost full, it tips the lawnmower because the bag is then heavier than the mower.
    It is quiet enough and easy to use. I, however, do not expect it to last many years.

    Just a heads up , every so often take top cover off exposing motor and fan , clean all grass out so motor can cool. I did mine after 3 years it was full of grass causing it to get hot and stop working...

    At age 74, weighing 96 pounds, with arthritis in both shoulders, my Sun Joe is so much easier to start and use than my gas mower ever was. Even manipulating the electric cord has become kind of a dance for me. I’m so glad I’ve found the right machine to keep me mowing!

    Very happy so far with my electric mower. The handle on the grass catcher bag does snap off easily when it’s full and trying to lift off the mower to dump. Plus the bag is much smaller than a gas mower bag. But I love that it starts every time, instead of my unreliable, non-starting gas mower. This mower is also very lightweight! I can push and maneuver it with one hand.

    Unfortunately it simply stopped running about a year after I bought it. I called customer service and they said, "we will replace the motor and you can use the box to return the offending part, free shipping!" Two days later there appeared a completely new mower! I packed up the old mower and returned it. Couldn't be happier with this company's customer service!!

    This lawnmower is great for my purpose at my cottage which is not on even ground and lots of slopes. The lawn mower is light yet powerful enough to cut the grass even when a bit moist. Quiet and easy to store. I lost a bolt and within days of calling the company, they sent me the part all under warranty. I would recommend this for the machine's efficiency and the service you receive from the company.

    New Vs. Reconditioned

    What's the difference between New and Factory-Reconditioned?

    Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
    • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
    • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
    • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 120 days.
