I like the Miracle Trimmer, but it might as well be an oversized paperweight as it doesn't fit my Stihl electric trimmer. The Trimmer was supposed to have universal fittings, but the main nut is to big and when I tried to get help from Miracle Trimmer as to whether I was fitting the Trimmer to my existing machine I didn't receive it. Right now the Trimmer is in a draw collecting rust.
