I love the motor although I have not performed any maintenance on it yet, then again, it hasn't needed anything other than fuel. I find it very reliable, easy to start, idles nice, lots of low rev power, and it is quieter than others in my stable. I love the reach. The collar on mine has not come loose, it stays where I tighten it. I find it heavy but I am a smaller guy. I try as much as possible to balance the weight, so that I am more or less at the fulcrum point. This reduces the effective reach but also reduces the strain on me. I can only run it for a couple of hours at most. If I only have a couple of branches to do, that is a different story, I can get closer to the engine end and reach out farther. Would I buy it again? Probably not. I would opt for something lighter if I could get similar reach, but that is not through any fault of the tool, it is my limitations. For someone stronger than me, or if you don't have to run it for hours at a time, I highly recommend it.
