great purchase
This was a very useful purchase for so many reasons. It has proved to be an extremely useful and quality tool so far . I expect that too continue even after years of being worked hard and maintained accordingly.

Love IT!!!
I am a 59 year old woman and my husband has a heart condition that prevents him from attending to the outside chores on 23 acres. I can use this chainsaw comfortably and safely. I cannot handle a gas chainsaw, so this 40V chainsaw was the obvious choice. It cut large fallen trees easily and did everything I needed it to do.

Far from perfect
The chain oil pump never worked and the factory said that it was back ordered, It wasn't the pump it was that the oil lines to and from the pump were reversed at the factory. After correcting this mistake the saw ran for about five minutes and died. I was considering buying another saw and using the original for parts but I changed my mind and ordered a different make by another manufacturer.

Cutt'en lil hammerknocker
I've been cutting fire wood, and clearing my properties for years, and I've never had a chainsaw I enjoy using as much as this 40 volt rig.
No fuss, no muss, just pop the battery in, check the chain tension, and go. I've dropped 23" sweet gum tree's with it, and sectioned it for splitting.
The oil reservoir is easy to monitor, the tension doesn't need tools to set, and I have yet to have a problem with this saw. I'm very pleased.

better than expectd
I purchased this saw to use as a backup to my gas chainsaw. I used it to cut up 3 dead trees about 12 inches in diameter. I only had to charge the battery once. Only wish is that it came with a sharpening kit. Have not used it long enough to test durability but it seems solidly built

Love this saw!!
I always had trouble keeping gas chain saws running. This is a great little saw for me. Just slip in the battery and go. I cut up a big pine tree that the power company cut down for me in just a little while. I am a 73 year old female living alone who likes to take care of things myself. So ladies if you need a good saw this is it. I also love the fact that you don't need tools for adjusting the chain.

Great so far
Have only had a chance to use the saw once so far, but made about 30 cuts through around 6 inch diameter logs for firewood with ease and without exhausting the battery. Looks like a well made tool. Perhaps it's a little on the heavy side due to the large capacity battery, but certainly not unmanagable.
