    Q:This trimmer comes with a 4 Ah battery. Will it operate with the 6 Ah or 8Ah batteries? I have a Ryobi mower and blower with an 40v 8 & 6 Ah battery respectively. Wondering if those are all interchangeable.

      Q:Anyone use this with blade head attachment for trees or bushes?

      A:  Hello, Kitt - Thank you for your question. The blade attachments would be best used for thicker brush, but would not be the best for trees or bushes. I hope this helps!

          Warranty is a scam
          I purchased this trimmer less than a year and part of the bump head broke off and can’t get the rest off to replace with a new one. I spent hours, days, months texting back and forth with Ryobi Digital Technology who made all RYOBI Tools and you will have to go through for the warranty claim. There is always someone different will ask me the same questions and give me the runaround. As of this day 08 November 2023 still try to get this fix. Good luck trying to get them to honor their warranty.

            Worked well until it broke!
            This trimmer worked well until it broke (as depicted), and I can't find a replacement part. For this reason I would not recommend purchasing this tool.

              Absolutely love it!!! 18 year old gas powered Craftsman string trimmer broke one too many times and I was tired of fixing it. Went out and got this and while pricy it works beautifully and makes trimming fun again! My gas powered string trimmer had a curved head end shaft which I preferred. I was actually able to use that end on this one. I was also able to swap out the string trimmer head too as my old trimmer head had seen better days.

              Really strong but quiet string trimmer that is fun to use and is much lighter to carry than a gas trimmer. I’m happy with it. Check out my review. Ryobi 40V String Trimmer - Expand it https://youtu.be/v7BvdsFUDIk

              Most Powerful String Trimmer I've Ever Owned!
              My specific model is no longer listed, but I'm sure its comparable to this model. I've owned my trimmer alongside my 40v mower for 3 years, i used to just purchase a new gas trimmer every year since they were so cheap and not worth fixing every time they break, but this Ryobi one just keeps going! Its literally outlasted any other string trimmer I've owned in the past, it has more than enough power to go through anything. I had to wait to buy a new bump feed head so I could finally trim.

                Carbon fiber is for real
                I have the "original" 40V brushless weed eater which I have been using it heavily for 2-3 years now for brush clearance. I finally destroyed the head of the string trimmer and decided to give the carbon fiber a shot. The carbon fiber is significantly lighter than the old version and it makes a big difference. In terms of power, it truly does have gas-like power. The battery lasts long enough to trim a yard. If you're trying to clear a large area, you'll need a few batteries.

                  Poor quality, poor performance.
                  Following all of the positive reviews I purchased this model. Unfortunately for me I'm the 1% who's trimmer came apart after only 40 minutes of use. The nut (now lost) securing the grass deflector vibrated off (with proper tightening). Minutes after that, the string completely retracted into the string head. Against my better judgement I disassembled the string head to uncoil the string and now after repeated attempts I can't get the string head back together. The unit and it's parts are back in the box available at my next yard sale. No, I don't recommend this model.

                    Several negatives
                    Upon first use, the edger guard for this trimmer was damaged by a small rock that was kicked up, for which I exchanged for a new one. Also, the center of the unit was smoking and extremely hot as the tightening screw managed to loosen thereby separating the drive shaft components and friction was creating the smoking. Third, the battery life, at 45 minutes was disappointing. Lastly, the trimmer head was difficult to reinstall - I needed to put the head in a vise to have enough hand strength to force the head back on. I will be returning this as it is a lot of money for so much failure and disappointment.

                      It’s a beast!
                      [This review was collected as part of a promotion.] I bought this a couple of weeks ago to replace my gas engine that was worn out. I’ve had 4 different gas engines that drive the Expand It attachments over the last 15 or so years. I’ve had Toro, Troybilt and the Ryobi 4 cycle. My attachments include trimmer, hedge trimmer, blower, edger and cultivator. This electric motor drives them all better than any of the gas versions I’ve owned. The torque is surprising. I recently bought the 40v HP mower and with 2 batteries, I can mow and trim the yard with power to spare. I’m thoroughly pleased with both tools.

                        Not recommended.
                        The service life is very short. I bought it for a year and used it occasionally. Now it's broken and the battery life is short.
