This is the 2nd Worx WG304.1 that I have owned. First one lasted 3 years before the carbon brushes gave out (could not find replacement brushes). It was a great saw that I used to cut firewood up to 16" hardwood logs. Have a generator on back of my John Deere tractor so I can take the chainsaw out in the wood lot and cut firewood where the trees are located. Only drawback with the chainsaw is getting replacement parts if you need to replace something, they are not available from all sources I've checked. This saw is much better, for me, than gas saw which I had hard time starting and keep running.
