I've had this tool for 2 years now and waited to write this review so I had enough time to properly use it. In short, this is a perfect tool for small jobs and clean up. It's more powerful than it looks and it easily chops through any branch you can fit into it's mouth. From time to time the chain will come off, this is no problem as it's very easy to open and clear it out. In fact, I believe the manual recommends you check, clear and clean the area it after X amount of cuts and I do that routinely to avoid this happening. I also purchased the extension tool, I've used it a few times but the tool itself is a bit heavy and even more so when you use this so just be aware. It's super easy to use, although I must admit I've sliced through 3 electric cords because I've have so much fun using it I took my mind off the cord so don't be me and pay better attention to what you're doing!
