This is the 2nd RY41002 that I have owned. I have a huge yard that I have to use my trimmer on about every 6 days 10 months out of the year. This is by far the best trimmer I have ever used, and I have been using trimmers of varying styles since the gas Sears Weedeaters of the 80's. This has the power of a gas w/o the vibration and noise. It just lays to waste anything I throw at it. My only complaint is that when I wore the last one out, I could not find a new one, I had to buy refurbished. I don't understand why they were discontinued. Love it!
