          Excellent Blower,
          [This review was collected as part of a promotion.] I won this blower in a raffle hosted by my homeowners association and fire wise group. It is an excellent blower with strong power and run time is decent, I am on 2 acres so I’m considering the backpack version as well so the wife and I can work together.

            Battery overheating fast
            Battery overheating every 3 minutes. This is very disappointing considering the money I paid for a tool that cant work longer then 3 minutes.

              Don’t buy
              Ended up borrowing a gas chainsaw to cut up a tree that fell down in our front yard. The first thing that happened was the chain got rough and wouldn’t slide in the channel after a few cuts, and I had to file the part of the chain that goes in the channel to get it to slide again. And the batteries do not last long. The five amp battery that comes with the 18” saw lasted about five minutes and the four amp battery I bought lasted about four minutes, and then doesn’t charge right away because it’s hot so I ended up borrowing a chainsaw to finish the job. If I could return this to Home Depot because I just bought it two days ago I would exchange it for a gas chainsaw.

                Bar Chain Adjustment
                Saw works fine when cutting bur chain bar adjustment housing is cheap plastic that easily breaks rendering chainsaw useless. This has now happened to me twice, on my 2nd chainsaw. Can't get the small replacement part Ryobi warranty people refuse to stand behind. Caveat emptor!

                  powerful but flawed
                  [This review was collected as part of a promotion.] I always start with 5 stars, and deduct for glaring design flaws. Our older 14" saw doesn't have a chain brake, which we decided we needed for heavier-duty work. My partner actually used this 18" HP saw to pass her professional chainsaw operator course; if you know how to read a stump or the butt of a felled tree you'll see not only the result of great skills but also a surprisingly competent saw. (The instructor, on seeing the result, said 'That's a picture-worthy stump!') My deductions: First of all-- believe all the reviews: Ryobi has NOT figured out how to keep bar oil from leaking out of their saws. My previous saw did it, this one does it, it's a perplexing thing. I really should deduct two stars just for this persistent, wasteful, destructive flaw. Second deduction: the guide bar is prone to loosening. Seriously, check the chain tension every dozen cuts or you will throw the chain. This can lead to injury or damage to the sprocket, the chain, or the (plastic) chain catcher. Despite these flaws it's a great tool. If you get one on sale, and look after the leaking oil and guide bar concerns, you won't be disappointed.

                    lots of power
                    [This review was collected as part of a promotion.] This will replace my gas saw. Very impressed with the power and the battery life. The battery also charges really quick. No fumes and low noise compared to gas saw.

                      Wish I had done this sooner
                      [This review was collected as part of a promotion.] I tend to cut small to medium trees on our property, along with the odd larger one. My lawn mower died, and based on recommendation from my brother, purchased the Ryobi 20 inch 40V HP. I was so thrilled with it that I sold my gas trimmer and bought another Ryobi. Then my wife asked me to cut down a couple of trees on the side of the house. I immediately put my 2 gas chain saws up for sale and purchased this, the 40V HP 18 inch. Hindsight is 20/20, I should have done this long ago. It may only be a bit lighter than my gas model, but makes working in the woods so easy. I was able start and stop at will, as I cut branches in order to fell the tree. It is so much quieter and generates no fumes. With no engine vibration, I had a better feel of the tree. I no longer need to store containers of fuel, and mix in oil, nor drive to the gas station 15 minutes away. As I am trying to stay in the 40VHP ecosystem, I have several batteries to pull from, so one can be on charge while another is at work. All that remains is to try larger trees, but I must say that at present, I am thrilled. Ryobi seems to suffer from a lack of respect by many tool users. It is highly unjustified. I have a more expensive brand in the city, and am not sure that it is any better in either build quality or function. To quote Mando, "This is the way."

                        Great on small diameter trees
                        [This review was collected as part of a promotion.] I bought this saw after we had a couple bad storms that knocked down trees and limbs. It does great on 3 to 4 inch limbs and trunks anything bigger and it wears battery down fast. One Sugar Maple about 18 inches in diameter and a fresh battery charged overnight barely makes it through one cut.

                          Plastic Junk
                          This chainsaw worked great until the other day when the chain slightly got stuck while cutting a tree. The chain came off the bar, so I opened it up to check out what was going on. After about 2 minutes I realized the only thing holding this entire chain and bar together is a bunch of tiny pieces of plastic. When the tree caught, the cheap plastic holding it together exploded and is not repairable. There's almost zero warranty on these things after the first 90 days and good luck finding parts.

                            Awesome saw.
                            [This review was collected as part of a promotion.] Bought this chainsaw back in the fall(oct) of 2022. This guy is a beast. Cuts thru logs with no problem. I even had some logs around a 24”-26” diameter. No problem cutting thru one side, then rolling the log and cutting thru the other. The saw has some nice weight to it, pretty balanced, and doesn’t clog up with the sawdust. Keep the blade sharp, and you’ll have no trouble cutting thru even the hardest wood.
