18V ONE+ STRING TRIMMER/EDGER WITH BATTERY & CHARGER is rated 4.3 out of 5 by 25.
Rated 5 out of 5 by from A really great trimmer I purchased this trimmer to replace an old gas trimmer I had. The ryobi trimmer was easy to assemble and I was up and running in a few minutes. The variable speed is a great feature, but the auto line feed took a bit to get used to. Once I did though it was easy to handle. This trimmer is much lighter than my old gas one, even with the 4ah battery installed. Switching between trimmer and edger was a snap using the rotating handle and the battery lasted long enough to do my entire yard but I did have to swap out the string cartridge. It was super easy by the way. So glad i switched to cordless.

Rated 1 out of 5 by from Not What I Expected Poorly made, and not worth the effort. My battery is a very snug fit, making it difficult to remove. More importantly, the line advance is lousy. Keeps getting jammed. I have to stop every 3 minutes to manually advance the line

Rated 1 out of 5 by from Missing parts. Bad customer service. Purchased in person at Home Depot. Can't finish assembly as the spool retaining head was not included in the box. I attempted Ryobi chat and was disconnected in the middle of the chat multiple times. The Customer Service 800 number answered in a timely fashion by a pleasant associate, but was unable to provide me with the missing piece, and suggested I call "Gardner" for help. I don't know who that is or what she meant by it. But they're not who I bought this tool from, nor the name on the side of the box. This is the third Ryobi tool I've bought this spring. And the last. Each one has had problems that required a call to customer service, and only once did the call resolve the issue.

Rated 5 out of 5 by from Wife loves it! Even cuts the tough phragmites as well as small grass areas that my 50" CubCadet cannot access

Rated 4 out of 5 by from Just short of perfect I bought this a few days ago on home depot online. Delivery was fast and the product was packaged securely. There is enough power in the trimmer to cut through weeds and grass effectively. Two complaints I have are: 1) the run time is low and could be improved 2) the design and placement of the string release could be improved so it doesn't run out of string too quickly. Nevertheless, it does the job as advertised and is an effective tool for small gardens.

Rated 5 out of 5 by from Great trimmer Although skeptical I decided since I had the 18V batts and an impact that both work very well and have held up I'd go for this trimmer/edger and see. Not disappointed, in fact impressed with how well packaged and ease of assembly as well as how well it has worked knocking down taller grass and weeds around the house. Cleans up nicely and can use, which I also bought, the hardx tipped trimmer unit for bigger/thicker weeds. After going around trimming had only used 1 bar on a 3ah battery. Looking forward to long, useful service from another Ryobi product.

Rated 4 out of 5 by from Freedom from cables and petrol I bought the product back in 2016. Works great until the guarantee runs out, Two motors both burnt out or stopped working around the time of the guarantee expiry. I'm now on my third. I have a large is garden with river bank where I have no access to power. The motors could be made to withstand a bit more work. Hence only 4 stars £60 every 4 years is not the way forward. Nothing on it can be refurbished

Rated 4 out of 5 by from Cuts and Edges Well I got this today and went to work getting all the corners of my yard sorted out. It does well cutting through tall grasses and some decently woody stems. I used it for edging my driveway and front yard and though it did a decent job. It absolutely crushes batteries though, so I would highly recommend having several. I've got the 4ah that came with it and two smaller ones that came with my drill. Between the three of them I can get a decent amount of work done before having to put it all back on the charger.
