I hoped that these trimmers would be powerful enough to cut through most things in my yard given that they are gas powered. The reality was that they could barely cut through a rosebush that was quarter inch in diameter (see pic). I’ll be returning them to Home Depot and going back to EGO battery powered trimmers.

    Great buy!!!
    [This review was collected as part of a promotion.] Good on batteries and smooth cutting. The articulating head makes trimming easy and fast. This is a must have for the serious landscaper. You can trimmer like a pro.

    I watched youtubes before I purchased this chain saw and it melted through limbs. I decided to purchase one and it would not wor . I went through an entire bottle of oil. I took it back and told Home Depot that I wanted to try a new one. Easy return and got home and this one melted through a shrub that I no longer wanted. It also sliced through limbs on other trees that needed pruning. I have never used a chainsaw before. This thing works great. Lots of power.

    Ryobi EXPANDIT 15" Articulating is LIFESAVER
    [This review was collected as part of a promotion.] The neighbor's dog, Rosco, doesn't particularly "like" me. When it's time for me to trim the row of 12 feet tall podocarpus trees aligning the property dividing fence, I've got multiple obstacles: 1) Rosco; and 2) The blue tarp my neighbor put up to block Florida afternoon sunlight from Rosco's turf. ENTER the RYOBI EXPAND-IT 15" Articulating Hedge Trimmer Attachment. Suddenly trimming the podocarpuses is NO PROBLEM.

    cuts very good but design is slightly awkward
    [This review was collected as part of a promotion.] Cuts very good but the design of the head tends to be a hassle when cutting my evergreen shrubs. It gets caught up in the branches very easily making it hard to manover.

    I have had this trimmer for about two years now. I bought this because of a monster hedge in my back yard. It's very tall and wide. I did not have enough reach with my electric trimmer. I also hate dealing with the cords. I was not sure of the quality because there are units out there that are called "professional" and cost a lot more. Let me tell you I have put this thing through the grinder and it has never given me a problem. I have cut branches a lot thicker than this is supposed to be able to cut. I have accidentally hit my chain-link fence more than once. I have also had it running for hours at a time. I do not see how spending more money could buy a higher quality trimmer attachment.

      This Trimmer Attachment Does The Task Well
      I purchased this trimmer to trim my 20, nine foot Leyland Cypress which in the past I have done with hand held scissor action trimmers or an electric corded trimmer. As stated in previous reviews my gas powered trimmer head combined with this attachment is a heavy handful but I am a slight (123lb) 63 y/o woman with arthritis so If I can do this, ANYONE can if they take their time. So far, I have trimmed the rear sides of the trees but can only work for 1/2 hour at a time - it's hot out there! The attachment easily handles the newer growth and if I encounter a 3/8th" branch it will eventually munch it in about 3 seconds so I utilize my long extension manual pole pruner for the thicker branches not to over-stress the capabilities of this trimmer head. Let me offer some advice for those who are trimming 'sappy' growth such as Cypress or pine, etc. Clean the sticky sappy residue off of the Ryobi trimmer blades after each use by brushing mineral spirits or paint thinner on the cutters, rinse, let dry and then oil the blades before each use. If you don't keep the blades clean, it will put hardship on the trimmer blades and the power head will suffer from overworking through the stickiness. I am posting a pre-trim photo of 14 of the 20 trees. So far, I am really pleased with this product and after I finish this project, I will post a follow-up photo The only daunting task ahead is getting high enough to safely trim the nine-footers down to 7 feet :)
