                  Buy something better - this unit is trash
                  Works great for years 1 and 2 - then they turn to garbage. I bought all the attachments so as each power-head failed i foolishly purchased another. Now I have 3 - none start. Wish i read the reviews outside of this site prior - common problem. Units work for a year or two then fail. 4-cycle is total garbage - no power and you can't use in all positions. Spend more and buy a better product.Just my $0.02.

                    We got our first Ryobi trimmer roughly 13yrs ago, still works, just needs some general maintenance but we recently decided it couldnt hurt to have a back up so we got a 2nd one. Everything we own is Ryobi and we've never been disappointed

                    The pole is weak and snaps in half.
                    [This review was collected as part of a promotion.] This is the second trimmer I have purchased that failed. My first trimmer was the 4 stroke. The shaft cracked above the attachment area and practically folds in half. This 2 cycle trimmer has done the same thing to me. From what I understand, if this happens, there is nothing I can do. The motors are still in good working order but I am unable to use either due to the pole snapping.

                      Seven years and going strong
                      I bought my RYOBI RY235SS from Home Depot about seven years ago. It’s a 2 cycle gas power head. I just changed the spark plug, fuel hoses, gas filter and carburetor today and felt the need to write a review. Before this trimmer I remember using a trimmer about a season or two before having to replace it. I was about to buy another and a friend told me about the RYOBI. They used the trimmer and cultivator head for their garden. He said he had his for nearly five years. I went to Home Depot and bought it on his recommendation. I started used pre-mix gas also. Seven years later and I’m still using it. The only reason I did the work today was the diaphragms in the carburetor can become stiff. The rest was a maintenance change since I had the carburetor off. Very few tools today are built to last. Since I bought the trimmer, I have bought the blower, edge trimmer, snow shovel, brush cutter and pole saw. Yes, the power head gets a lot of work. But I could not be happier. It’s followed me from managing 8 acres to now .5 since I'm retired. I just wanted to say thanks to Home Depot and RYOBI for a great product. I really believe this trimmer will outlast me now.

                        Solid Starter Gas Trimmer - Perfect for Attachments!
                        I’ve been using battery-powered trimmers for a long time, but I picked this 25cc 2-cycle gas model to get a bit more power and speed for my landscaping company, Trustworthy Lawn Care. Performance & Versatility: It’s a bit shorter than the electric ones I’m used to, but it’s quiet and has a decent amount of power. The main reason I got it is for the attachment capability. I use it with my tiller and my pole saw attachments when I need to take down small limbs on a job site. It handles those attachments like a champ. Handling: It feels a little small in my hands, so I’m actually passing this one along to my wife, who helps me out with the business. It’s perfect for her to use while I’m handling the heavier gear. Since it’s been a while since I used gas, I had a little trouble starting it at first, but once you get the hang of it, it runs great. Verdict: This is an excellent starter or residential trimmer. It’s not a heavy-duty commercial beast, but it’s reliable and the versatility with the attachments is unbeatable for the price. I’ll be picking up a couple more straight-gas units with more power for the crew soon, but for home use or as a backup, I highly recommend it! Key Highlights: Versatility: Works perfectly with Expand-It attachments like tillers and pole saws. Size: Compact and lightweight—great for smaller hands or residential use. Power: Good "zip" for a 25cc engine. See my full setup in action on TikTok @PrimevalLogic!

                          Unable to get parts if there is an issue.
                          After having this product for approximately 1.5 years the primer bulb needed replaced. Long story short, parts were not available at HD. Went online, parts did not work. Several carbs later, still did not work. So do not buy this product if you plan on using it more than a year. I challenge any Ryobi employee to get this product running again with the available product the general public has to use!! I bet they won’t even try!! That says a lot. America are you tried of crappy products!

                              Complete trash.
                              Absolute piece of crap. Zero stars if it had been an option. I have owned this less than a month. I have worked on the string and string head for more time that I have actually used it. String will not advance with bump. Took head apart to restring. Now head will not turn to close. Absolute garbage. I want my money back. I am furious.
