I was really excited to test the the new Troy-Bilt string trimmer. This weed wacker is extremely powerful heavyweight. The manual is detailed and assembly took 5-10 minutes. The fuel and oil tanks were easy to locate and fill. The primer worked great and the trimmer started after several attempts. This is common with a new trimmer. Needs to break in and let the fuel circulate.  The trimmer does a great job at cutting down the grass and weeds. The only issue my wife and I had with the trimmer is the weight. The trimmer is too heavy for use for a long period of time, but excellent for a one house quick use. You will get a workout using the trimmer. Overall, I am impressed by the power, quality, and design of the the trimmer, but would rather have a trimmer that is more lightweight to use daily.
