Rated 5.0 out of 5.0 by THE ONLY SAW FOR ME, DO I HEAR AN ECHO? LISTEN! I bought this saw last fall to replace the one that I had for around 30 years. The Echo 650. The most dependable chainsaw ever made. I used it year after year on the farm and in the Hunting business that I own and operate for the past 31 years. We use them all the time. We call this one Hoss and I also bought the small one that we call Little Joe. I will never switch. People say there are better saws out there and I say, "how can it get any better than one saw lasting for nearly 30 years." It can't. ECHO, echo, echo. Do I hear an echo. Yep that's my saw.

Rated 5.0 out of 5.0 by Great chainsaw I read as many reviews on chainsaws as I could find prior to purchasing the Echo CS-450P saw. All reviews of the Echo saw were positive, but I was still a little reluctant to purchase. After looking at many different makes and models, I purcased the Echo. I have not regretted my purchase and would not hesitate to purchase additional Echo products. May 24, 2015
Rated 5.0 out of 5.0 by Easy starting ! Good Power I was a Husky owner and proud of it bought 3 back in the 80's along with a cs 3400,guess which one started last year, that's right the cs3400 ! the Husky ALL have bad coils No more Huskys ! its ECHO or nothing ! April 14, 2015
Rated 4.0 out of 5.0 by runs forever but.... I own a landscaping and tree service company. I run ECHO everything from string trimmers,blowers and saws. now for the good stuff. This saw will run forever for any homeowner and professional. If your planning on felling trees I suggest getting the 550cp for extra 20 bucks. This saw will bog out when tested, I've ran Stihl and Huskee saws and this one is always my first choice. Like I said great saw and extremely comfortable to use but for an extra 20$ you wont regret the extra power when you need it. November 28, 2011
Rated 5.0 out of 5.0 by Nice Chainsaw. Cut up a downed pine and pecan tree with this thing. Took me the better part of the entire day, it never even slowed down. Nice sharp chain, cut the pine and pecan like it was butter. Hope it lasts a long time! November 22, 2011
Rated 5.0 out of 5.0 by great product, as usual! This cs450p replaced my basically new stihl ms250(also 45cc). the stihl was always leaking bar oil or fuel or sometimes both! Also, on numerous occasions the Stihl failed to start. I found myself using old faithful( my 18 year old cs3400), which as never let me down...... ok, it did once! A few years ago I had to replace the primer bulb due to cracking(age). I also have a pb2400 leaf blower that was purchased at the same time as the cs3400 and I've never had to fix anything on it.....ever........... Same is said for my Echo srm230 trimmer(which is only 5 years old)........This is why I went with Echo again! November 13, 2014
Rated 4.0 out of 5.0 by Great saw for the price. I purchased this saw about 4 months ago. I have since felled 14 standing dead Oak trees (killed in last years drought). The 450 has preformed great. Only complaint would be fuel tank size. Wish it was larger capacity. Overall very happy with it. August 22, 2013
Rated 5.0 out of 5.0 by Runs Great I bought this chain saw as a replacement for the one I had. The few times that I used it ran and cut great. The engine is powerful and does not bog down. Very good saw. October 23, 2014
