Quick And Easy Chainsaw Gets The Job Done.
This chainsaw is great for the homeowner. It runs off a 40v Lithium Ion Battery that lasts up to 40 minutes. There's no need to worry about buying gas and mixing it with oil. All you have to do is put a charged battery in it, top it off with bar and chain oil, and away you go cutting logs.

The saw passed all my tests. I highly recommend it.

I have owned this saw for about 10 months. I have cut about 10 face cords of firewood with it. I like it for the features and convenience of being an electric tool rather than gas. But my home owner quality gas chain saw seems to cut faster and I don't understand why. I'm thinking it is because of chain speed. I notice that the rpm is 4800 rpm. The corded electric chain saws that Sunjoe sells have rpm of 6000. It would be nice if Sunjoe would give me an answer.

i used my first one for a year without any problems at all, till it bound up . Sunjoe replaced it , since it had a 2 year warranty. The replacement i received had something rattling in the housing. They quickly sent a new one to replace that one .
