Great Tool
Have had pole saw about a month now! Excellent for trimming; better design than the old 20V I had. I recommend upgrade to 40V as battery lasts longer and design an impressive improvement!

This is one of 7 Greenworks tools I own and this one is a life saver. We had these branches hanging over the side corner of the house that the only way to get to them was to hire someone to climb up there. I purchased the Pole Saw and was able to reach the branches and cut them off with ease. We also had some tree branches near our pool that were giving us problems but the Pole Saw solved it as well.. The ability to remove the extension and use the tool with a shorter length was a tremendous help. WIth the battery installed, it requires a strong hand to maintain the cutting when fully extended. It can be done without too much difficulty.

No More Gas
Assembled, charged the battery and added bar/chain oil. Cut up several small trees and limbs that fell during a recent heavy, wet snow storm. Was pleasantly surprised on how well it cut. I'll be getting rid of my gas powered saw.

Great for cutting shooting lanes in woods!
I am an avid deer hunter & have clear shooting lanes for my arrows & bullets to travel through is a must. I used to haul hand & gas-powered pole saws into the woods. Hand saws didn't leave any scent but don't cut large limbs well. Gas saws leave petroleum smells in the woods that deer hate. I bought this saw & use canola oil for lubricating the chain & both of these problems are solved. I've got an extra small battery from my grass trimmer & a large one from my chainsaw so I can trim for a long time. Great product!

Keeps On Going
This is the first Greenworks tool that I bought years ago. It still cuts like a champ. It ran circles around my previous gas pruner. I love the angled head feature to reduce pinch. I also like how it breaks down and can easily be put into a car. I have only used it once so much that the battery about ran down, but I was also run down. I had another battery, but it was time to quit. This purchase led me to also purchase a Greenworks chainsaw and other 40 volt Greenworks tools.

Great tool, works very well
Bought my 1st 40V G-MAX tool 3 months ago ... this Pole Saw was my 6th purchase. I've had a "115VAC corded" pole saw since 2012 (lighter shade of green brand "X" and really wanted to go cordless. Instead of the separate intermediate pole like this Greenworks, my corded one has the two ends telescope out from the mid section. With the mid pole in place, the Greenworks is about the same length as the corded saw fully extended however it seems to be a bit stiffer / not as flimsy as the telescoping corded saw. Their lengths are also similar with the intermediate pole removed vs. the telescoping saw fully retracted.

Trimmed all the dead branches out of the 3 trees in my front yard and pruned back a few other trees as well. Maybe 2-3 hours total work; pole saw run time maybe 20-30 minutes total and used only 2 bars or 1/2 of the 2Ah battery ... pretty efficient battery usage considering it is a standard brushed type motor.

I checked the chain speed after using and found the sprocket turns at 4650 RPM which calculates out to 340 IPS (no load speed). The corded one goes quite a bit faster as expected (8160 RPM or 598 IPS). I had not used my corded one for at least a year, so I was surprised there was this much of a difference. I certainly did not feel this Greenworks was lacking in speed because I was perfectly happy with the rate at which it cut through branches ... maybe chain speed is not as critical for this type of work. For comparison, it's chain speed is 4x the 85 IPS rate that my 18V 10" brand "X" chain saw runs at (which IS painfully slow for a chainsaw).

Definitely like not having a CORD for this type of tool though, and as I said above I did not feel like it was lacking in speed or power during use. With the 2Ah battery, this tool weighs 9.66 lbs. where my corded one weighs 9.00 lbs. Remove the intermediate pole and the Greenworks is only 8.42 lbs. However in use, the corded one is actually heavier as there will be cord attached to it constantly tugging downward.

Would this tool be better with a more powerful & efficient brushless motor ?? Maybe ... as long as there would be no added weight. Compared to the other Greenworks 40V tools i own ... 16" chainsaw, 21" mower, 14" string trimmer, blower/vac, & 20" snow thrower ... I feel a brushless motor is mandatory for these tools to get the desired performance and decent run time per battery charge. For this Pole Saw though, the brushed motor is fine.

Very happy with all of my Greenworks 40V G-MAX tools as well as the performance and run time you can get out of the 2Ah, 2.5Ah and 4Ah batteries.

So easy to use.
I have had my Greenworks Cordless Pole Saw for a year now. So easy to use. Can reach branches without having to get a ladder. Came in handy last year after hurricane Irma. Always have the battery charged and was able to get right to cleanup.

Decent power and extension, long battery life run
I have several oak trees which need pruning periodically. I had a Black and Decker pole saw with the old (non lithium) batteries. Short run time, declining power. After a few years of use, the batteries died. This saw is a clear improvement. Far better and more consistent level power. Good cutting of branches up to about 8 inches diameter. The angle of the saw is definitely an advantage over the B&D. Thus far I cannot find any weaknesses, particularly for this price point. Although not a commercial tool, it certainly is a very good and practical homeowner which can save me (and you) many hundreds of dollars in pruning costs.

We had some smaller maple trees growing over our fence and this tool cut those higher branches amazingly. It went through the branches effortlessly and was a lot of fun to use.
