Just wanted to circle back on this thread. A month ago, I bought the Kobalt 40v Pole Saw from Lowes using the 20 off 100 coupon generator that's out there for a grand total of $160. I charged it that night and the next day used it for a couple of hours trimming 4-5 trees pretty heavily after a big storm cracked several limbs on each. I used the 3 cut method and generally cut the pieces in 2 foot lengths so it was quite a bit of cutting. When I quit for lunch, the battery was down to one bar from four to start. I recharged it through lunch and used it again in the afternoon to continue cutting.
All in all, it was well worth the purchase and I had no issues with the saw. I never felt like the job was too big for the saw and it cut relatively quickly. Not as fast as my gas chainsaw, but I didn't expect that. I cut everything from 1" up to about 7-8" which required cutting from both sides to get it all the way through. Occasionally when the limb would start to droop and it would bind on the blade, I did worry about it breaking the saw. The rod between the battery and the head was plastic and I did get some flex in those situations where I had to pull the saw out of the limb binding. I was very careful, but I think it would break pretty quickly if I was careless and I'm sure a good gas powered echo or stihl wouldn't have much of an issue with this, but it would have been $600 more.
Since then, I've pulled it out twice, popped the battery in and quickly cut one or two branches on some other trees and I think that's where this really shines. The ease of use in pulling it out, cutting something, wiping it down and storing it are really great.
Biggest dislike is that it's yet another battery form factor and charger, but I got over it.
Hopefully I won't need it, but it has a 5 yr warranty which I think is longer than all of it's competitors. I would definitely buy again for occasional use around the house
