Greenworks40V 16" Brushless Cordless Chainsaw, 4.0Ah Battery and Charger Included

I've used this chainsaw several times, enough to feel comfortable writing a review. Firstly, it has plenty of power, I've cut through 12 inch trees with it...no problem.If you're sawing down a tree or two and don't mind taking a break, then one battery will probably do. Heavy use means a second battery. The way I use the saw, two batteries means between 2 - 3 hours of cutting depending on how far I want to deplete the battery and the diameter of the tress I'm cutting. It takes about 1.5 hours to return 3/4 charge to the battery and 2 hours to return a full charge to zero.Bottom line. The power is there. It's easy to use and will fit the bill for most homeowners. It's quiet. It's smooth cutting. It's friendly for first time users. In my opinion, it feels like a well built, quality tool.A second 4ah battery is a requirement for all day work, but occasional users or those doing small jobs, like cutting firewood for a camping trip or cutting down very small trees, will probably find one battery pack will probably work well.*UPDATE* Downgraded to FOUR STARS. Excellent saw, took down some big trees with it this weekend, but the Tension Knob has plastic teeth. It's already starting to wear out. Luckily, it's a cheap part...only $3 online. I continue to recommend the product, but a extra tension knob isn't a bad idea, just google Green Works Part 34108583. In the tool's defense, I'm pretty sure I over-tensioned the chain.*UPDATE 5/28/2014* I've used this chainsaw EXTENSIVELY in the last six weeks. This morning, I had a number of logs to saw up. I started with a pile of longs cut to approximately 4 foot lengths, stacked 3 or 4 feet high and about 8-10 feet long. Big stuff, many were at least 1 foot in diameter. I needed about three charges to get through it all, but I started with two full batteries, so that meant stopping only briefly to put the spent battery on the charger while the full one was running. (Batteries never actually went to zero. I recharge when the indicator light shows a low battery.) The saw powered through everything, I had zero problem cutting it into firewood sized lengths.I replaced the chain tensioner that broke and haven't had any more problems. It's clear to me that I had over-tensioned the chain before, that said, the part should be made of metal, but it's easy and cheap to replace and I now have a couple of spares if it happens again. As far as I'm concerned this is the best electric chainsaw on the market.*UPDATE 4-25-15* I've been using the saw for a year. I broke the tensioner last year by over tightening the chain (user error), it's been fine since. I've already cut down at least 5 trees with the saw so far this year. Still going strong. Excellent saw. I continue to recommend TWO batteries and TWO chargers, it really speeds up big jobs. Bumping it back up to 5 stars.

The main issue with this saw is the brand new chain cutter links are so short that they look like a worn out chain that is about to be thrown away. But I cut half of a cord of blown down oak, the limbs and the 20" trunk using less than 3 charged batteries, WOW! I was so impressed that when my wife (we are both recently retired) told me she wanted to upgrade from a snow shovel to a little snow blower, I recommended that she buy the Green Works 12" snowblower package for about $200. No snow yet on the apron in front of the house yet to try the snowblower yet, but the extra 40v battery and extra battery charger looked like the perfect addition to the chainsaw! We can now go out in the morning and I cut oak firewood while she shuffles blocks of wood and branches for about 45 minutes, we split the wood with a 20 ton gas powered splitter pulled behind the 4 wheeler, go back home and put BOTH batteries on the 2 chargers on a timer set for 3 hours to avoid cooking the batteries (especially during end of the day charging), eat lunch and relax a bit and then go out in the afternoon and repeat the process with a LOT less noise and no yanking on that recoil starter rope of my 30 year old Jonsered 535 gas saw that has no decompression valve! ( I had shoulder rotator cuff surgery a couple of years ago) We are VERY HAPPY so far, I just hope the batteries last a couple of years. As far as the folks making comments about the oil tank leaking, or the chain falling off, or the chain oiler not working (enough oil for about 1 hour run time) or short battery run time, and regular bar oil works just fine by the way. I honestly believe that they are wanna-be lumberjacks that have NO past chainsaw experience to know how to set-up and safely operate such a well built product. I honestly (honestly, for ONCE in my life) highly recommend this CHINESE product! It works GREAT! As I mentioned earlier, the cutting links on the original chain are too short to sharpen more than a couple of times, but that's the only issue I have had after cutting my second face cord of big oak today! This saw is NOT a toy! We have so far cut 2/3 of our firewood to heat our home this winter!Update... attached pics are the 1/2 cord of oak wood I cut using a total of 3 charged batteries.The trailer bed is 8 feet long, 40" wide, and the pile averages 26" high. I like the saw so much I bought 2 new Oregon chains #R56 (fits PERFECT!) and use my same old Timber Tuff CS-BMM benchtop electric chain saw sharpener with the 3/16" wheel (@$50) for a REALLY sharp chain with great results, much better than a Dremel type tool with a 5/32" bit I used at first on both saws! Timber Tuff does not have a 5/32" grinding wheel available for that model sharpener. Even though it is 1/32" wider than the Greenworks and Johnsered 5/32" chains specify. It only makes a little nick in the main part of the chain that has never been an issue, and the saw power is not affected by the slightly deeper cut the chain makes. Don't worry, be happy! And GO CUT SOME WOOD!

It works. It is much lighter and easier to use than gas chainsaw. And it is enough for pruning and cutting mid-size trees. Battery life is something what you expect (~40min ) . Basically you can cut one tree and do few bulk cuts. Recharge time could be less for Li battery currently it takes few hours to recharge.

The saw was well designed. There is a big knob to adjust the chain tension, very convenient.I cut down and limbed a 10” oak very quick and easy, plenty of power and plenty of battery power.

This chain saw does a great job! It is very easy to use, it cut through an 8"-10" oak tree that fell in our side yard like butter, and is relatively light with long battery life. Couldn't be happier with this purchase. I highly recommend this product!
