We love this lawn mower!
This mower is phenomenal. It is so much better than our old gas mower, it's almost difficult to find the words. It was easy to assemble, it's so light and easy to use. It does a great job mowing our lawn. The first time we used it the lawn was higher than usual, the mower plowed right through. The battery charger is easy to use as well. The battery slips in and out of the mower for charging.

I would recommend this mower to anyone, including older people that need a mower that is light, easy to use and still gets the job done.

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 Mower
I have only used it 3 times at this point, but it has proven incredibly lightweight, easy to use, and not nearly as loud as my previous gas-powered mower. I'm very satisfied and would highly recommend this mower to someone who has a similar size lot to mow.

Excellent Product and company!
Love this lawn mover!! After using it for about a year, the handle broke off the side. I called the manufacturer and was expecting them to tell me that I was out of luck and would have to buy another one or try to get it fixed. Instead, they immediately told me that they would ship me a brand new unit !!! WOW!! Amazing customer service! I received the unit a week later and they paid the shipping for the new one an for return of the broken one.

I also have the battery operated snow blower, which I love as well. The only comment is that you really do need at least 2 batteries for both units (if you have a large lawn/driveway.

Overall -- Great Company to deal with and Great Products!!!!

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.

Perfect little mower with big mower power
This was a housewarming gift from my father. It was easy to assemble, very light, and easy to use. It has 6 height settings but I've only use the highest two. The mower is quiet and efficient, the bag collection works great.
I am very pleased with this product and i'd recommend it!

Great Product
So far this has been a great product. I have a small yard (3600 square feet and this has been working great so far. I'm seeding a new lawn so have not had the opportunity to see how long the battery would last, but I'm guessing it would at least get my lawn mowed without having to re-charge the battery. I love the fact that I don't have to use gasoline. I would highly recommend this product.
