Rated 4.8 out of 5 by 90 reviewers.
Rated 4.0 out of 5.0 by FORWARD HANDLE 100% PLASTIC Born and raised on a farm. Used many saws over the years Wards brand, Sears brand, McColloch, Poulin, Stihl. My Father and I cut and split 7 chords of wood (split by hand) per year to heat our home, I know the chainsaw world very well. I chose this 18" saw because I am not as young (and strong) as I used to be so a lighter saw fit my needs. The chain is not quite as agressive as I am used to however it does cut suprisingly well even thru locust and oak. Engine power is matched to the weight and bar size perfectly. Very easy to handle, maneuver and formost easy to start. I am quite dissapointed the forward handle is made of 100% plastic, not rubber coated aluminium like the photos I looked at on the ECHO web site prior to buying. Would have rated 5 stars otherwise.

Rated 4.0 out of 5.0 by Works well I good reviews and took a chance on Echo, a brand that I wasn't familiar with. It is much better than the Poulan Pro that seized after only one year of use. I like the 5 year warranty. The only issue so far is the chain and bar noise. I've never had another saw with this kind of noise. Sounds like it's not getting enough oil. But it works great and I can see the oil in the cuts. I guess it's just the way it is. We'll see how it holds up. November 20, 2014
Rated 5.0 out of 5.0 by 5 years now, still love it! Not a minutes problem with the saw, and have used it quite regularly. With a little bit of care and maintenance, this saw should last a long time. November 29, 2014
Rated 5.0 out of 5.0 by Awesome saw I bought this saw after getting extremely frustrated when trying to help a friend cut down a tree. I had 2 Poulan Pro saws and could not get either one to start and run. I threw them both to the side and ran to Theisens and bought an Echo saw. I have used it many times in the last couple months and it has started and ran perfectly. I would recommend this saw to ANYONE. Well worth the cost difference. November 19, 2014
