Rated 4 out of 5 by from Best Warrenty Saw works well and is powerful but battery does wear out fast and needs short pauses between long cuts but it is a great tools just have extra battery’s on hand. The customer service I have encountered tho was beyond exceptional and for that reason alone I would recommend them. Let’s face it everything breaks but when it does u don’t want to deal with bad customer service and employees trying to refuse to fix the problem. Let me tell you they helped me thru that very upsetting time and did not leave me alone. They where very understanding and kind even tho I was angry. Thank you Ryobi company.

Rated 5 out of 5 by from Doesn't stink from 2-cycle pre-mix! Isn't as loud as 2-cycle chainsaws either! And I don't have to drag a cord a couple hundred feet like my electric saw. Plenty of power from the 40V HP system. I took down a 10 inch and and 8 inch tree then trimmed and cut up the 10 inch till I was down to brush before the battery wore out. Comes with carrying case and integrated scabbard. Used about 3/4 of the chain oil in two battery charges. Many features to reduce kickback risk. It is no lumberjacking tool but is great for my occasional landowner use.

Rated 5 out of 5 by from Awesome Awesome Awesome!! I bought this 40V HP 18” Brusheless Chainsaw and it works amazing!! No need for all that 2cycle oil and gasoline or wasting gasoline and getting all messy. It’s battery powered and saves you money and don’t have to worry about all that smoke that you get from a traditional gas powered one and all that loudness. Never thought a battery powered chainsaw would do exactly as a gas one can do. Plus it way more quieter and I love the safety switch it has so you won’t accidentally hurt yourself or others . I feel like Ryobi is going to be in my life for a while keep it up Ryobi!!! 10 stars!!!

Rated 5 out of 5 by from Best electric chainsaw there is I bought this chainsaw to cut up a tree that fell in my yard, the tree was probably 14" wide and atleast 40 foot long cottonwood tree and this chainsaw ate it up in no time at all without any hiccups whatsoever. I was honestly so surprised at how well this chainsaw cut as compared to a gas powered chainsaw, the fact that it was powered by a battery is mind blowing.. granted I have multiple 40v batteries, they really don't die and if they do the battery charger charges them incredibly fast. If you want to skip the gas and want a chainsaw that cuts as soon as you pull the trigger, buy this.. you won't be let down

Rated 5 out of 5 by from Worth the wait Originally I was waiting for the availability of the 16" version-- not sold in CANADA! I was even willing to drive down to the States but, Covid killed that idea. So it was a pleasant surprise when Ryobi came out with an 18" version with heavier battery for $30. more! Love this thing. So light with a decent lasting charge. No it does not have gas power, but what it does have is good power to knock down 16" trees on my property. This is a consumer chainsaw and as long as you don't give it contractor abuse it should hold up fine.

Rated 5 out of 5 by from 18" is where it's at ... I've been waiting and watching ... finally saw a good review on the 16inch (because you don't get the full length to cut with) and was planning on getting that one, but 18inch came out before I could get to the store and went for it... no doubt worth it. *first day I cut down my planned 3 plum trees, cut a half cord of 4-8in branches of oak/hickory, and then cut various things that looked like they wanted cutting around the property line ... still had 2 bars left on battery when done *tip carving was a little difficult with this, but that's not the main reason I bought it
