18V ONE+™ LITHIUM+™ 16" MOWER WITH (2) 4AH BATTERIES & CHARGER is rated 4.5 out of 5 by 284.
Rated 4 out of 5 by from Nice Cut, Powerful, Good Battery Performance Out of the box with a fresh battery charge, I mowed 800 sq feet on 25% of the battery charge on grass that was 4 inches tall, using setting 3 on the mower. The unit responded well, although a bit rigid to turn. The mulching part didn't snap in all the way and needed a good push to lock in. Overall performance was very good. A bit disappointed that the fold-up isn't as quick or tidy as some other models and that it doesn't stand-upright. I'm concerned that the handle locking clips may not last with the folding and unfolding. The carry arm at the top is very handy! Overall, looks like a good mower and hope it stands the test of time.

Rated 5 out of 5 by from Love this mower We have a good sized corner lot that I can mower about half of on one set of 4ah batteries. It use this mower in the morning close to my neighbors so I don't wake them at 8:00am. I also trim around the several trees and beds we have. I can then finish the yard with my 8+ year old gas mower. The Ryobi is very light so it is easy to push and then around our trees, sidewalks, and flower beds. I may check to see if the new 6ah batteries will fit to now more with it. I just wish more Ryobi parts were stocked at Home Depot. HE only had the blade for this mower. I do my own service work and try to keep my equipment well maintained so they will last.

Rated 5 out of 5 by from 8000 square feet of grass on 2 1/2 4Ah batteries! I just mowed my very thick, fertilized lawn that has been growing for more than a week. I usually use a 6.5 hp, 21" cut gas mower to do this. I thought there was no way this little 18+ was going to cut it. I am amazed! It did a beautiful job. I mulched most of the lawn and then had to collect some of the clippings where maple tree seeds had fallen. I may never use my gas mower again.I also loved the quick height adjust with just one knob to adjust the height and the easy to put in mulcher plug and easy to use catcher, I am giving this a high five stars. For anyone who has an investment in 18+ batteries and the 18+ line like I do, I would not hesitate to buy this.I am glad i did.

Rated 4 out of 5 by from First time First time I used it, it was great. Finished my backyard on the set of batteries it came with. About what I expected. I’m satisfied with it, I have a decent size front and back yard. I bought a second set of batteries, so I don’t have to worry about waiting to cut each yard. I’ve read many horrible reviews about this mower, I’ve seen none of the complaints though. Batteries maybe, but I Again expected that. Lasted about 35-40 mins on one set. So unless you’ve never owned anything battery operated, you’ll complain no matter what. It’s meant for your regular surbabanite yard, nothing bigger. I have no complaints so far.

Rated 5 out of 5 by from Well worth the money I'm very pleased with this mower. Had it for 2 months now. Gives a good clean cut, and the grass catcher works fantastic. I did notice 'clumps' when I used the mulch feature, but if I ensure the grass is dry and slow down my walking speed to give the mower time to mulch up what it's cut, then it works very well. The size is perfect for me, it's lightweight, and very easy to maneuver. And, it's very easy to keep clean; I take a couple of minutes and brush it off (especially the underside) after every use. if you let the clippings stuck to it dry, it does become much more difficult to clean. Overall, I'm very pleased with the mower and the batteries.

Rated 4 out of 5 by from Great for the power! I live on a quarter acre lot with a small yard. I didn’t want to mess with gasoline yard tools Due to the small size. This mower is great at cutting and bagging. Only lost a star because some of the parts that I think should be higher quality are made from plastic. And you have to keep an eye on the level of grass in the bag because it will bog down the motor if it gets to full or wet. This mower gets the job done great! And I have a lot of people stop and ask how the electric mower and yard tools are. I tell them you can’t beat it!

Rated 5 out of 5 by from Very Impressed On First Mow I bought this mower in a combo set with the trimmer and blower. When i unpacked it, I became a little skeptical as it was all made of plastic. I wanted to put it to the test, so i set it to mulch with a height adjusted to 2, in fairly long grass. To my surprise, it outperformed my expectations! I did not feel it slow down at all until about 30 minutes into the mow, but it still went through the grass very easily. I'll be curious to see how well it holds up over time and to see if the batteries continue to hold their charge, but I very pleased with this purchase. I will update my review in time if things change.

Rated 5 out of 5 by from First Time Mower This was my first lawn mower purchase and first time experiencing mowing a lawn. I have seen many Ryobi reviews and also my favorite color is green so i decided to try out this mower. I must say that it is super easy to use and requires no prior mowing experience to master. After losing one of the nuts inside the mower that is used to tighten the handles I was a little upset but I was able to retrieve the nut from the inside and place it back in it’s place. Since then I have had no issues. I would definitely recommend this mower to anyone wanting to try a battery powered mower or a beginner mower like myself.
