Great Saw
I've had several chain saws over the years gasoline, electric and rechargeable. I am extremely happy with this saw for general trimming at both of my properties. I have yet to find anything wrong with the saw.

I was really surprised at the way it makes short work of all my trimming chores. It's light enough to use for a long time and the battery doesn't die before I'm ready to call it a day.

Decent With Problems
I have not used it a lot. I was pleased with the cut rate on a number for smallish trees. Fast cut. So far battery life seems decent. I am on the first charge.

Issues: packaging for shipping completely unacceptable. Every thing loose in the box to bounce around in transit. Particularly concerned about battery. You should not screw with Li batteries. Chain oil all over everything including manuals. Manuals pretty decent.

It uses an excessive amount of chain oil. Chain oil leaks out when it... more
Pros: Easy To Use, Quiet, Fast
Cons: Packaging

Clearing Some Of A Wooded Lot
Haven't used it on anything over about 3" in diameter so far, but it makes short order of that small stuff. So far I love it because I don't have to pull my heart out to get it running and it's so lite it is really easy for me to handle. I'm 76 yrs. old and not in the best of shape anymore, and it's easy on my energy level. I'd buy it again !!!!!
Pros: Easy To Use, Light Weight, Exceeded Expectations, Reliable
Cons: Expensive

A New Chain Saw In Town
I have been waiting for this chain saw for a long time. It is a perfect selection when it comes to my requirements for a specific type of chain saw. I am most happy to know that I can start to work with minimum of delay. When they (Greenworks Company) combined the tool with a Lithium-Ion Battery, it was a perfect match. The Lithium-Ion Battery is a wonderful wonder in development in power instant and long running. I do not see the possibility of returning to a different type of chain saw... more

Over Came My Disability
I am a veteran (Vietnam) with Neuropathy in both hands. This saw has allowed me to complete the third day of cutting/pruning. I have cut branches more than 2 inches without a whimper from the saw. I have another 2 weeks before I'm done and I'm sure the saw will last. I especially like the portability.
Pros: Easy To Use, Light Weight, Exceeded Expectations, Quiet

Good For "occasional" Use
It is a battery operated saw. It is inexpensive. If you use it for occasional downed branches under 6 inches, you will be happy. If you are sick of having a gallon of pre-mix sitting around waiting to use it, you'll be happy with the battery system. If you expect to replace a gas saw and get the same performance.........happiness will not be in your future. Common sense should have told you that already. If it hasn't, you may want to hire someone to cut up your firewood who has more... more

Meets Expectations
Used it for one day. So far, so good. Does the job cutting and pruning small limbs from juniper trees. Battery still had plenty of juice by the time I was ready to call it a day.

Of course, being electric, it runs a tad slower than a gas powered saw, but that was expected. Very convenient as compared to having to gas up and keep pulling on a rope. Seems to be well made but the 4amp battery does add to the weight.

Great Product, Greenworks Customer Service Needs Help
I was delighted to discover Greenworks products. A dream come true, to put loud and messy gas tools behind, along with endless cord pulling. When I found the Greenworks products on the Power Tools Direct website, I dug in and researched the chainsaw, hedge trimmer, and pole pruner.

I phoned Greenworks directly to get more specific product information. I was surprised that their sales reps were not real eager to help or offer info. They also quoted a huge shipping price, twice the price... more
