I am an once or maximum twice a year user of chainsaws for a few hours each time to cut firewood or remove fallen or falling trees. I have a regular gas chainsaw, which has worked with no maintenance for over two decades of such use. I wanted to try an electric saw to see if I should get it as a backup and eventual replacement.For the test I wanted to cut down a dead ~14" birch and two thin ~8" maples. The chainsaw came preassembled and the battery charged very quickly (~1h). Everything was intuitive, so you just need to add the chain oil and it was ready to go. It started nicely and cut well (of course, new chain). It did a quick work of the big birch, but about 50 min into the project it stopped. No warning, as the battery continued showing 4 bars. Just stopped and that was it. So, I got ~25 min of continuous operation out of it, primarily on the birch. Next day I recharged the battery. Again it took little time. Didn't check exactly, just a few hours and it was ready to go. Added a little oil (it used whatever I had the day before sparingly) and finished with the maples.All in all, a very pleasant experience, efficient, clean and quiet. On the negative side, very short work time. To remedy that, instead of returning the saw, I thought of getting a second battery. Yes, you can - for $10 more (on Amazon) than the entire chainsaw with a battery! That didn't make much sense. So, in essence you get a disposable saw. Every few years as the battery dies (and Li-ion batteries die after a few years as you know from your phone/ipad etc) you buy a new chainsaw.To summarize, if your requirements are limited to less than half hour of continuous work and you need it reasonably often, this saw might be a better option than a noisy and smelly gas saw. The reason I mentioned "often" is because if you use it like me, batteries die with time whether you use them or not. But it didn't work for me, so I'm returning it. When new battery technology comes out, I'll give it another shot. I did like it.l about a battery chainsaw, but not anymore. Plenty of power and battery life. No more pulling a cord endlessly. I would not go back to gas again.was surprised to see a 60 volt for this price$156 usually won't include battery and charger. 40 volt ones go for more. my guess is the ad said "old school' and didn't have auto tensioner but nut and bolt on for the bar. i have a saw with the auto tension and hate it, most on line posts agree "dumbest invention ever" a common comment some makes may work better than others. but mine is a pain. so when i saw this with nut and bolt i had to have it . i can adjust chain just as quick and more accurately and for a$100 less the saw works great just pull trigger let it rev up and works as well as my 42 c.c. gas saw . one review said it was just a toy. it does take getting used to battery powered saws they feel funny at first but this is no toy. . can zip through 12 inch log no problem. didn't give 5 stars unsure of battery life but i 've cut quite a bit and so far so good. my opinion like the headline said this a steal update Oct 29 the 2.5ah battery won't last all day, enough to get truck load of lengths in then block for an hour 5 ah battery costs over $200 tip Upstart replacement chains CSC-R56 sell on Amazon for $30 a six pack and work just as wellI ordered this saw a week into the Covid-19 isolation after reading its reviews and watching a lot of video reviews of many different brand battery powered chainsaws. Not many available on this saw, tho. But I determined the features I wanted and the pricepoint I could handle. This saw did not have the easy tensioner of some, but after a bit of research, I found out it came with an Oregon chain and blade, that is high quality and readily available locally, important to me. I have over 40 years experience with gas saws, but at 70 years old, I have fiddled around with them long enough. It is very satisfying to not have the noise, fumes, and hassles of a gas saw to worry over. When you start this saw, there is anshort lag from the time you pull the trigger, and when the saw chain is at max speed. Read the manual! Do not start a cut until the chain is at full speed. I have used it to cut down and cut up a dead large dogwood tree...ran smooth and no problems. I like the light weight, just a bit over 13 pounds with the battery installed. I like the trigger start up, no idling saw to worry with. I will use it a lot more tomorrow now that I have a feel for it. Once I down a tree, I will use my battery operated Worx jawsaw to do the principle limbing and trimming, then switch over to this saw to cut firewood. I cut about 2 cords every spring for use in our home wood furnace. I will also carry this saw in my truck when 4-wheeling in the woods and when camping for cutting camp wood. I am happy with it now as a new owner, and if any problems develop, I will add to this review and adjust my ratings accordingly.Not looking back to exchanging my gas powered Echo for this saw. This one feels just as powerful, cuts better (probably the new chain), and is so easy to bring it out for even small jobs. The gas powered one was always a hassle to get started and warmed up.
