I love It
[This review was collected as part of a promotion.] Lots of power, easy to use compared to other brands I had in the past. It's compatible with a lot of attachments, like edger or even a blower. Love at first use.

        People should review only AFTER actually using the product !!
        Trimmer was cheap compared to other gas powered trimmer and that was the selling point for me, as I have a SMALL yard. Against my better judgment with other Ryobi products I purchased this trimmer. Couldn’t even finished the job before the engine failed, same day. I took to HD for a replacement & I was actually advised at HD to use other brands as Ryobi are famously unreliable and creates a lot heated discussions for the employees with customers. I also had purchased a Ryobi chainsaw that never started and leaf blowers that would only last 30 minutes. Just stay away from this brand and if you’re looking at the reviews, do take into consideration if the reviews was made by someone AFTER actually using the product.

          More power than i EXPECTED!!

            Blown through at least 4 of these
            I’ve had a bunch of tools for the expand-it line for over a decade now. The cost of the accessories was the main reason I’d replace the it when the motors failed after a season or two. The last two I bought barely made it a year. It’s almost a subscription service at this point. If your going to use this regularly, it’s not going to be worth the cost in the long run. Spend a bit more now, save the headaches. I’m sitting here with another dead one and plan on the tossing everything.

              Who needs attachments if engine doesn't run?
              I thought the was a great deal because of all the attachments. I bought the combo pack about three months ago for over $500 with the pole saw, trimmer, edger, blower and hedge trimmer. The first day I got it I attached all different attachments and was pretty happy with the operation of them all. Then.... the problems begin. I tried to use the trimmer for the 4th time and can't get it to start. I tried fresh gas, checked the spark plug and every other recommendation in the owners manual. I have always used ethanol shield mix or low ethanol gas as recommended in the manual. Finally took it back to HD for repair but haven't heard back yet. I miss my old 4 stroke Craftsman. I had it over 10 years and changed the spark plug once but was thinking since I just purchased some acreage I needed a new one. Oh yeah, the pole trimmer has leaked bar oil in my shop where I store it so the exposed 2x6's are soaked in oil and there is a spot on the concrete. I will never buy another Ryobi product again. Go with an echo or sthil for gas power and Dewalt or Milwaukee if you want the drill/impact set. DO NOT BUY THIS!!!

                    I bought this trimmer at Home Depot last season. I bought the tree trimming attachment. It worked just fine the first time I used it. I sold my Troy Built trimmer because this one was newer. That was a huge mistake. I have not yet had a pleasant starting experience with this piece of junk since the first time it was used. Several times I have brought this out to trim and edge my yard after mowing. More often than not, the sun will set as I am yanking away tryimg to crank this disappointment. I have been so irritated with this device that I may never buy a ryobi product again. Off to find a replacement that actually works. Please save yourself the frustration and find another product, preferably another brand!
