            Cheap plastic Ryobi needs to do better
            I got my Lawn mower today opened the box which showed No signs of damage and the first thing I see is broken pieces of plastic laying around the box. The plastic is so cheap the shipping of the product had smashed under the housing of where the batteries are kept. There was no packing materials to protect anything. This is ridiculous Ryobi $700.00 you need to do better this left such a bad taste in my mouth I will be switching All my power tools over to Dewalt.

              Cheap garbage
              RYOBI quality has gone down hill over the years. Mower is 2 months old and the bag/mulch handle is broken already! Only used the mower about 6 times.

                Love the mower. As a female senior, it is easy for me to handle and does a professional job. I have discovered that I can cut better than many of my past lawn services, it leaves a very professional cut. I can also adjust the setting levels to get a balanced level looking lawn. Have used it twice thus far. Exceeds my expectations, but the mower requires high intricate attendance to operate. Love the fact that it has 2 batteries and that it folds up neatly in the garage.

                Great product but flimsy
                The self propelling lever broke on the second use. It's held together by a very small and thin plastic piece

                  One mow in - so far so good! The adjustability of the self-propelled feature is excellent and easy to use. I am contending with some steep terrain in my front yard as seen in the photo. The mower is lightweight compared to a gas model. This means it doesn't always get enough traction. Not a big deal but I would like to see a more aggressive tread on the wheels. Right now it just seems like a token design. Battery use is on par with other items- actually probably pretty good considering the powered drive. I'm satisfied. This mower was expensive, but will pay for itself this summer by NOT paying somebody else to mow.

                  Better than gas mower
                  I am impressed with this mower! Replaced a Snapper 21". Things that are better: powerful, mulches better, quiet, push start, folds up in seconds, battery charge in less than an hour, side shout installs in seconds, variable speed paddle on handle, AWD for hills, one handle for adjusting all wheels all at once, no mulch plug. Most of all no gas and maintenance! The only thing not as good is sucking leaves up compared to the Snapper Hi Vac. I will upgrade to the 10AH and use 6AH for blower.

                    Ran good until......
                    Lasted a bit over a month. Good Mower, battery not good.1st mow, no problem, 1 batt did the job. 2nd mow, the 2nd battery had to kick in thankfully comes with 2 batteries. After 2 more mows, one battery showed an error message, a day later off the charger, the battery catches on fire! Luckily I was home, took action and avoided my house burning down. Tried calling Ryobi - over 2 hours on hold, can't reach anyone. The faster text 1-800-525-2579 - a joke..just as bad! Email, HA! Returning junk!

                      Not exactly what you want
                      Ok so I bought this as a replacement for a gas mower. In my case, not a good idea. This mower does ok if you have a ‘manicured’ lawn. Not so good if you don’t. Not only that but the batteries a total of 3, are only lasting about 45 minutes all together. If you have crabgrass and chicken foot grass you’ll have to mow over it 2-3 times to cut it. if your grass is more than a couple of inches tall, you will have to clean the exit shoot every couple of feet. pictures are with the cut set at 3

                        Batteries spend more time charging than in use
                        I have been using the Ryobi for over 3 years now. Even upgraded to the more powerful model. Today I used 3 fully charged batteries to cut my lawn. After less than a hour of stop and go usage BOTH batteries were down to one blinking light - needing recharging. Only was able to ALMOST complete my back yard. Still have to do the front - and the next door lawn as well. Sad that I can last longer than the battery- and I am 63 years old AND take pride in cutting my lawn C’mon - do I have to purchase 2 more batteries- for a total of 5 ( 2 for my mower and 1 for the hedge trimmer) just to cut the lawn completely at one time 🤷🏾‍♂️
