Easy to use.
I would've given this chainsaw 5 stars, if not for two things, 1st chainsaw doesn't come with oil,(can't use it, out of the box) 2nd I would've liked a longer Battery time (charged battery a full day before using). Other than those things, Good weight,, easy start up, Stop is on point. Cutting down a 10foot Yucca, was nothing.

I had it for more 4 years!
I cut hundred trees on my back yards, mostly 5-6 inches tree diameter.
Perfect tool for a first chainsaw. Powerful, no kick back, few maintenance.
No loud, perfect to be use Saturday at 7:00!

Gets the job done!
This tool has been a miracle worker on my twenty acre homestead. I purchased the chainsaw after watching how easily my son mowed his lawn with his Greenworks battery powered mower. No more hassle, mixing gas and oil and trying to store it for future use in a traditional, gas powered chainsaw! Just keep chain oil in it, and the battery charged, and cut away!

GreenworksTools - Cordless Brushless Chainsaw
I'm a retired Forester and am well accustomed to using chain saws. I purchased the battery chainsaw because as I'm getting older and not able to fight with a gas powered chainsaw to start I wanted this one to go when I say go and stop when I get tired. LOL
It works great for what I need it for. I recently cut down 3 trees I no longer wanted and it made quick work of the project. Plenty of power and long lasting as well.

Great battery chainsaw
Great tool, easy to handle yet powerful enough for bucking an 8” log like butter. Battery lasted me 4 hours on one charge. Very happy with my purchase

Good saw but not as good as the original
Over all it's a good saw but not as good as the original. I purchased the same model in 2014 and used it extensively. Current version takes longer to get to speed and chain spins longer after trigger release. Power is good once it's up to speed, just not as zippy a performer as what I was used to.

Not the Sharpest Crayon Saw Review
Rather than pay a few too many dollars to have someone cut down various trees and overgrown bushes, I decided to purchase this item and cut things myself. I’ve never used a saw before. I’ve never had so much fun using a power tool. You just put oil in it, put some safety gloves on, hold it steady, and saw to your hearts content. I named her ‘Snaps’. It is a delight to use this tool.

I wonder where this battery powered chain saw has been all my life! It is a thousand times better than a gas powered one. I enjoy not having to smell the odor of the gas powered ones. I purchased the larger battery and it lasts a lot longer than this ole lady can work. I am so impressed with the power! LOVE IT---LOVE IT---LOVE IT!!!!!!!

Very impressed
I bought this a while back for light yard work and it worked fine. Really easy to use and much more convenient that an gas saw. Then we had a big willow fall at the back of our yard. In the last few months i have made many cuts more than 12 inches and one around 30 inches. The saw has been great. It will only do 30 or 40 minutes of active work before recharging but that is OK for me. If you are thinking "it will do the regular stuff but what if ...?" then i have been there and it was great.
