        Q:Mine constantly shuts down when it meets any resistance while trimming. It’s not overheating, nor is the grass getting tangled in the head. Why is this happening?? It appears to have a useless automatic shutdown safety feature.

          Cut through anything
          [This review was collected as part of a promotion.] The weeds in my new community are out of control they grow over night. I decided to buy the Ryobi cordless trimmer but knew the string option was not ideal. I opted to buying the expand-it with the brush cutter attachment. What can I say, absolutely worth every penny this thing shred through the whole yard. I am super impressed with this product and glad I added to all the my Ryobi collection. Without the battery this this is fairly light, once you add the battery they it becomes heavy. I had to take a few break as if is heavy to worth with but I prefer it over electrical. I love Ryobi expand it line. Way to go!!!

            Long time Ryobi supporter
            [This review was collected as part of a promotion.] I just had to retire my trusty gas powered Ryobi weed eater that has been in my family for years. My dad first bought it years ago and then passed it down to me when I bought my first house. I was so sad to let it go, but I can honestly say I am extremely impressed by the power and precision of my new upgraded Ryobi 40v weed eater. The ease of use and convenience truly is the best upgrade I’ve added to my tool stack. I’m excited that this was my first battery powered Ryobi purchase and it definitely won’t be the last. I look forward to adding to this new collection. Attached are some photos of my old reliable laid to rest.

              Trimmer attachment wiring became un-wound.
              The coils that go around the square gear on the trimmer attachment have started to unwind. This is preventing me from being able to install the trimmer attachment into the head… can’t even use the trimmer. My other attachments still fit in the main unit so I know the issue is due to the coils coming undone. Check out the picture. This is my second ryobi string trimmer. I like these products, however, their quality is dropping since I got my first one back in 2021.

                Good trimmer. Little heavy. Slow to Charge
                [This review was collected as part of a promotion.] Over all I am satisfied with the quality, power, and expandable capabilities of this power head unit and attachments. Charge last longest on lightest shortest attachments, longer than you want to be in the heat working anyways. Charge time is a bit slow. Unit is fairly heavy and shoulder strap can dig into fresh sun burn. Maybe a leather sleeve or foam pad would offer more comfort. Expandit mulching head accessory is a must for stubborn weeds and shrubs

                      Light weight and easy to use
                      [This review was collected as part of a promotion.] I just bought this trimmer yesterday and was pleased with how lightweight and easy to operate it was. I was also impressed how long the battery lasted. If that wasn’t enough, changing the string was a snap! I was so pleased with it, I was going around asking the neighbors if they needed some trimming done and showing them how light, powerful and easy it was to use.

                        Solid weed eater!
                        [This review was collected as part of a promotion.] I’ve had this for a few weeks now and it’s a solid trimmer. Comfortable to use, plenty of power, and long run time. Nice addition to my Ryobi 40v family of tools. The bump string is easy to use. No problem refilling with new string. I’ll be using this to do some leaf shredding in a trash bin at one of places with tons of leaves. This will help break them down quicker for my compost heap. Overall, great value for a solid gardening tool. Very happy with my purchase.

                          Does the job
                          I have lots of weedy areas and some lawn to maintain. I put this trimmer together in just a few minutes without looking at the book. I haven't had to change the string, so I can't talk about how easy or difficult that is. As far as performance, I am satisfied. It made quick work of weedy areas with weeds a foot high. I like the variable speed. Battery charge lasted longer than I did. I was able to trim a large area and still had power left. The battery re-charge time was decent. So far, I am happy with the machine.
