Great product at at amazing price
I have had this saw for six months now and I love it it’s the best 30 cc chainsaw in its class against the Stihl ms170. It’s light weight easy to handed and good peer to weight ratio. I was cutting 13 inch logs for fire wood and it had no problems doing it. I love Echo products and recommend it to any one who is looking to buy their first chainsaw or someone who needs a light weight saw. I love the 5 year warranty and have always had good luck with Echo Products.

The little Chain saw that could
I purchased this chain saw to replace an incredibly hard to start Ryobi.
I have used it twice.
First time was to remove a fallen 70+ year old pine from the back yard fence of a neighbor. it chewed through vine, pine, limbs and everything's I could cut.
Recently I had an Oak Branch fall in the yard. Did not hit the house. So, Filled it, primed it, and pow, started right up and got to work. Made short work of a treemendous job.

Great smaller sized saw
[This review was collected as part of a promotion.] While this saw is on the smaller end of Echo saws, this saw does pack a punch. It will cut and not so heavy so you can cut for a longer time. I have a bigger saw but this is my go to for it’s sheer size and you can hold it longer without tiring out.

CAPSCREW SAFETY VIOLATION
THIS CHAINSAW IS DANGEROUS DUE TO THE CONSTRUCTION HEAD TANK IS MADE OF PLASTIC AND THE CAPSCREW ATTACHMENT IS NOT SCREWED TO METAL INSTEAD IS GLUED TO PLASTIC; WHILE CUTTING BRANCHES THAT CAPSCREW CAME OFF AND THE SECOND ONE RIPPED BY THE CHAINSAW FORCE I WAS IN DANGER OF LOOSING MY ARMS LEGS “THE MANUFACTURER SHOULD HAVE CREATED METAL CONSTRUCTION SPECIALLY FOR THOSE CAPSCREW THAT HOLD THE CHAINSAW!!!! THIS IS A SAFETY VIOLATION!!! I USED THIS CHAINSAW ONLY 5 TIMES HOW CAN I TRUST IT NEITHER I CANNOT SELL IT USED PUTTING OTHERS AT RISK ITS A BAD INVESTMENT!!!

Should have bought the Ryobi battery powered
Title says it all. This thing is so hard to start every single time. I only used it for cutting like 3 times or something small and not even that much, just here and there. Even my neighbor said it’s junk.

Junk
This thing hates to start. Had several months now and used maybe 30 minutes total. It doesn’t like fresh gas or anything. It just doesn’t like to start. Hopefully echo or Home Depot will take it back. I want the Ryobi battery chainsaw.
