Rated 5.0 out of 5.0 by Great saw extra cc`s worth getting on the 18inch Worked and started as described . Fast cutting, weight just right, good color easy to locate in the woods. Worth a little extra getting the 45cc on the 18inch bar size. Ordered online, quick shipping, packed securely . Would recommend . February 1, 2014
Rated 5.0 out of 5.0 by Great saw I bought this saw after experiencing poor quality and support from Stihl. This Echo has lots of power, starts easily and warranty is much better. Appears to be well built. Very satisfied with my purchase. April 22, 2015

Rated 2.0 out of 5.0 by Not a good choice Got this shipped to me from HD it arrived today. I assembled it, fueled it, added chain oil and tried to start it. I almost dropped it on the floor the first time. I'm 6'4" and 225 and I could NOT pull the rope fast enough to generate a spark and start the machine. After several tries, I removed the spark plug and the rope pulled freely. Put the plug back in, same thing. Finally, in desperation I placed it on the garage floor, put one foot on top of it and pulled the rope, It started on the first pull. I let it run a few minutes, shut it off and tried again holding t in my hand. Same thing. I called Echo, not much help there, they said to take it back to HD and they would ship it in for repairs. I then called a local "servicing dealer" and asked for suggestions. They said to bring it in and they'd look at it. Very disappointing April 28, 2015
Rated 5.0 out of 5.0 by Awesome saw- powerful and hungry!! After a recent tree clearing experience, it became obvious that my 14" Echo saw just wasn't the right choice for large projects that involve numerous 18-20" diameter trees. I considered a couple of "cheaper" saws, but after reading many reviews and spec sheets, decided to maintain my brand loyalty to the one who has never let me down. I chose this particular saw because the 45cc motor would have plenty of power to turn an 18" chain, as it usually is spec'd out for a 20" bar. And right that was! This saw has plenty of power, and never bogs down when you push the limits. A couple of features that I found real nice are the pump primer which delivers fuel right to the carb., and makes startup easy, and the location and quality of the air intake filter. The filter is more out of the way of wood shavings then on other saws, and the filter itself is much more like a K&N automotive application then a typical cheesy 2-stroke filter. Great investment, and well worth the price!!! May 20, 2013
Rated 5.0 out of 5.0 by ITS A KEEPER Hurrican sandy blew trees down like match stixs. My old MAC 3200 was not going to handle the 4' diam tree in driveway. I picked up saw and cut for 12 hours day one and 4 hours day 2 and 6 hours day 3. The saw always started went threw 2 chains in 3 days. The 4 foot diam tree 100' tall was a good challenge . the saw worked like a champ . the tree was laying on a house . Had to use a ladder to access the top portion of the tree .. worked well off the ladder and upside down cuts. Its a keeper . November 6, 2012
Rated 5.0 out of 5.0 by Best Chainsaw I have ever used This thing is unstoppable! I am absolutely shocked how well this saw performs. I was cutting through 30 inch logs and it did NOT bog down on me. the power is amazing. It does not smoke like other 2 cycle chainsaws do. It cut those logs like a hot knife through butter. Dont buy the cheapo homelite piece of junk. Spend the money and do it right. This is truly a fantastic piece of machinery. Good is never cheap, and cheap is never good. Buy the Echo cs-450. My name is Skippy, and I approved this message. March 12, 2010
Rated 5.0 out of 5.0 by Makes the work actually fun! Someone mentioned it uses too much bar oil. It uses what it needs to make cutting easier. Just keep a sharp chain and it cuts trees like butter. Someone else complained about the requirement of a medium grade octane. I have found that all power equipment runs better and with more power using a good quality premium gas. I almost bought a smaller chain saw, however I am really glad I did not. September 2, 2012
