Trimmed 3 large trees, including a pine tree. Worked as designed. Light poles and sturdy. The attachments are easy to use. Clean branch cuts. The blade can cut thick branches. However, anything over 2.5 inches in diameter, I recommend using the saw attachment. I cut a 2.5+ inch diameter hard branch with the blade. After a few hard pulls on the string, I was able to cut it but the center of the blade chipped a bit. I had to re-sharpen it. Other than that, a good purchase. I didn't have to hire a tree-trimming service.
