It's a good little estate saw for $100. Auto oiler and very light. I have an 18' bar on it, so it CAN cut a fairly large tree. It is clearly labeled "Not For Everyday Use", so I alternate days that I use it. My son has one just like it so we're covered if we want to use one two days in a row. I fully expect it to last 56, maybe even 58 hours! Maybe more!!
