          Great product for the value
          The product is great, it’s lighter then I thought.

            Lightweight but powerful!
            This mower was a great addition to the rest of my 18v tools. It’s lightweight so it’s easy to move, control, and store, but it also has great power and cut my grass much more consistently than my old gas mower that had the blades replaced recently. I have just over 1/3rd acre front & back, and was able to get the whole lawn finished within the 4 batteries that were included. Great value to get a 20” mower and the batteries/chargers and still be able to use the batteries interchangeably.

              Best lawnmower ever owned
              [This review was collected as part of a promotion.] This lawnmower is bulletproof. Had it for 2 summers same battery it came with and performs like it did when i took it out of the box. I have a decent size yard so I cute the front yard one day through the battery on charger then cut the back another. Now it not like the battery is even close to dead when I go to charge it, only use 3 dots out of 5. The return on investment is their, number one gas lawnmowers are similar in price or maybe more plus no trips to the gas station or oil.

                  powerful, easy, reliable!
                  [This review was collected as part of a promotion.] I’ve been using my Ryobi for 4 years, and it is a dream!!! Starts so easily, runs quiet but so powerful at cutting our grass, even when it gets high. Easy to use with the self-propel - just love it!!! Good run-time on one charge as well.

                      I've used the mower only twice now, and already the rear deflector has come off and I can't figure out how to put it back on.

                        Electrical burnout
                        I bought the older model in May 2019. This summer it started cutting out then quit. Upon inspection the connector burnt out. The only repair Center is two hours away. How can this happen to a machine that is supposed to have so many safety features. Yes it’s 5 years old but only used in the summer on a small yard. Very disappointed is an understatement. Why should I purchase a Ryobi products. This machine should last for many many years. If it didn’t quit my review would be a 5

                          Very solid value
                          [This review was collected as part of a promotion.] Used this for the first time today and am definitely satisfied! Setup was a little confusing but once you understand how it works its very simple. Endurance was basically as advertised, maybe even a bit longer! I had let my lawn get pretty bad so this had its work cutout for it.
