Rated 4.5 out of 5 by 277 reviewers.
Rated 5.0 out of 5.0 by Very nice chain saw I had a Poulan chain saw for 10 years that finally died. I purchased this saw and it has worked great. I've cut a lot of wood with it and starts and runs great. I read from some pro operators that if I used 89 fuel and added an ethanol stabilizer to the fuel that this newer engines will run great and it has. The hand fatigue after 8 hours of cutting is much less my previous chain saw. I wished I would have bought this saw years ago instead of struggling with Poulan. I also purchased an 18" PowerSharp bar, chain and stone that helps so much with keeping the chain sharp. June 23, 2014
Rated 5.0 out of 5.0 by This chainsaw rips Adjusted the carb right out of the box. Put in pre-mix fuel and bar chain oil. Pumped primer once and it started. I went through 1 tank of fuel. Saw worked like a champ right out of the box. Very happy after reading some of the bad reviews. January 15, 2013
Rated 5.0 out of 5.0 it`s a great saw I love the placement of the controls and the easy starting.I just like way that the saw operates and handles. I would rather have a Echo than a Stihl saw any day. May 25, 2015

Rated 5.0 out of 5.0 by terrific chain saw gets the job done. returned a husky two days after purchased and bought this instead. so glad i did. world of difference. should have bought echo first. would not have wasted time and cleanup would be done by now. May 22, 2015
Rated 4.0 out of 5.0 by Easy to start I have had a good experience with a Echo blower and bought the cs-400. It starts well and has good power. I am happy w this purchase. May 23, 2015
Rated 4.0 out of 5.0 by It's a chainsaw and it cuts wood It does what it says it will do but it's a little hard to start at first. Lot's of pulls until it eventually goes. Once it does go it needs a little warm up time to go full throttle. Other than that I don't have any complaints about it with my average use. May 20, 2015
Rated 5.0 out of 5.0 by GREAT!!! This is the Best chainsaw I ever purchased, I bought all the other brand and this echo starts with 1 pull. I just Love it May 20, 2015
