I've been cutting an average of 4 cords of firewood for 36 years. I have used just about every brand of gas powered saw at one time or another. I've gotten fed up with today's 2 cycle engines to the point where I've gone to battery and electric for blowers and trimmers. Now trying to do the same with the chainsaw. So I decided to try the 80v with 18" bar and 2 AH battery.

The first thing I did was read the owner's manual (yep, my wife was surprised too). I didn't want to make a stupid $300 mistake. Somewhat out of curiosity, I removed the cover, bar and chain. I oiled the bar and chain upon replacing and adjusted the tensioner. With a fully charged battery I went at it. Started easy with small limbs that didn't require splitting. I got 83 cuts with the first battery charge and 87 with the second. Not exactly the 150 cuts Greenworks claims. I've now had 8 sessions, cutting red oak logs up to a 20' diameter (only 1 that size). I've cut quite a bit in the 8 to 16" range (all oak).

Now I'll backtrack a little. I have 4 acres of woods with house, workshop and shed near the middle so I'm never far away from electricity. My mode of cutting is to run the saw out of gas, set it aside, split everything that needs splitting, gather the wood onto a small trailer, pull it (with lawn tractor) to my piles, unload and stack (repeat as necessary). Then hope the saw will start again with a fresh tank of gas. My trailer is called a 10 CF but if you measure the bed and do the math it's 7.5 CF. So a rounded trailer load I estimate to be 9 CF. My minimum requirement for this battery powered saw was to cut at least a trailer load so I could keep busy during the 30 minute recharge cycle. Well, it has done that with every cutting session. The range has been from just barely a trailer load when cutting the small stuff up to almost 2 trailer loads when cutting the perfect logs. Perfect for me was 6 - 14" diameter well dried oak where the density has decreased but is still great for firewood. By comparison, I average 2 1/2 to 3 trailer loads with any of the gas saws I've used in the past. Even though the saw has met my minimum requirements I'm not giving it 5 stars because of either the yield per charge or the total cost. If either the cost was 25-30% less or my yield was 25-30% more it would get 5. I do think this saw will handle 60-70% of my need thus reducing my reliance on the gas saw. It works for my situation but maybe not for everyone. I hope this review will help you decide. If anything changes significantly, I will update.

Update 4/16/17: Now I've used this saw for just over a year and have cut over 5 cords of hardwood. As it turned out, I never cranked up the old gas saw. I even dropped and bucked a 26" diameter oak with this saw. All with the original 2AH battery, bar and chain. While I'm very pleased with the saw, I still won't give it 5 stars for the following reasons:
Like others mention, the oil reservoir leaks,
The oil cap cross threads so easily and so often that it started popping off while running. I did find out that some caps from quarts of motor oil have the same threads. I punched a small air hole in the top and have been using it for a couple of months now. No cross threading and no popping off. Go figure,
And the "string" that keeps you from losing the oil cap could be stiffer so it will feed back into the reservoir more easily. But now that I'm using motor oil caps that's no biggie as I have an endless supply.
I'd like to see the bucking teeth be a little longer. Often, they don't grab as well as I would like,
Last but not least is the price. I see it has gone up rather than down over the past year. I might not have given this thing a try at the current $324 price. And though I'm very interested in the blower and string trimmer, I can't justify the current $378 price for the combo.

UPDATE: 10/1/17. Update of sorts. Amazon ran a one day sale on the 80V blower and trimmer(one included a 2AH battery and charger that I couldn't resist. So I did pony up. So far pretty good. I'll be reviewing those products separately very soon.
