great, but could be better
This mower is perfect for cutting my wife's and my cemetery plots, which is why I bought this product.I have two suggestions though. I know it will probably cost more, but some people don't have any way to store it in a tempered area. It would be better if the battery was removable. Also, the handle should be attached to the mower with thumb screws to make transport in a cars' trunk doable. I was able to make the handle change, so it was not a problem for me personally, but most don't have the know-how. Otherwise, it is a great product.

First mowing and I’m very happy!
Just finished a 30 minute mow of my backyard and I am very happy with the performance of my Sun Joe cordless 14 inch mower! It arrived at my doorstep last evening, took about 15 minutes to put together and then plugged it in to charge in the garage for a few hours. This morning before rain set in, I turned it on and it did a great job, was quiet and efficient and a joy to use! Thank you SunJoe!

Product ok, but great customer service
Lawnmower battery completely died in less than a year, but customer service was amazing and immediate in honoring the warranty, and sent a free shipping label to return the lawnmower and sent a new replacement lawn mower the next day, before I even got to Fedex to return the broken one. Appreciate the no hassle quick response.

I am a divorced mom in my 50's. This product was very simple to put together and it is even easier to use. It is very lightweight. Once it is charged I can mow my entire front, back and side lawns. If I let the grass get too high then it has to be recharged to finish. For me it is great that there is no cord to worry about and it is even better not to have to worry about the gas and oil mixture for the gas mowers. I love it!

Great lawnmower for senior citizen!
This lawnmower is just great and runs so quietly and is light-weight for me..a woman in my seventies! I can trim so easily around places that I couldn't get to before..weed-eaters were too heavy for me. Also can do some banks at the front of the property that are steep..too dangerous for a riding lawnmower . So easy to charge the battery,too. And great not to drag electrical cords around!

I had a very small area to mow and this mower was not up to the task. Short battery run time, but the biggest problem is you have to babysit the charging process or risk damaging the battery or charger. I can't believe you guys can't make the charger a smart charger. Charging time is limited to 4hrs, so any more and you can damage the charger. I know. Too much hassle to set an alarm or reminder every time you charge. I ended up returning for a refund after killing one charger and only mowing 3 times. On the plus, your customer service was very good, when I called about the not charging issue explaining I left the mower on the charger overnight, I was sent a new charger very quickly. Still didn't want to babysit the charging process.

I had previously owned the electric one that you had to use an extension cord and frankly it was a pain in the butt, not the mower, but using an extension cord. I don't have a big yard and when i wore out the other mower, I really wanted to get a cordless one and this fit perfectly! It was super easy to put together and get it charged! I now mow my lawn in probably 10-15 mins and no nasty cord to get in the way! I affectionately call this my Lady Remington!!! It's a perfect mower for what I needed.
