I was wondering if anyone has ordered and used this trimmer head that attaches to a weed eater? My mother is interested in purchasing one of these, but she doesn't want it if it's junk. I looked at the reviews on the "As Seen On TV" website and the reviews aren't too favorable. It has a 2.2 stars out of 5. My mother doesn't have good luck with weed eater string and since this trimmer head eliminates the need for string, she was getting pretty excited about it. I just don't want her to waste her money if it doesn't work very well.
