Works very well and feels well built.  Handle is contoured to help me get a good grip and I can swing through weeds with ease.  Small saplings up to maybe 1/4" get chopped with one swing, and I wouldn't really use it for much bigger on purpose.  I just wish the blade  face was a little longer...  I had one years ago that had to have been a few inches longer.

EDIT:  Later last season, maybe the 4th use of the grass whip...  The metal part separated from the wooden handle and went flying about 60 feet.  I am just so glad it was aimed towards the woods, and not the house, cars...  kids.  Uggh.
