I ordered an edger attachment for my trimmer. My trimmer isn't a split boom so just the head comes off for the attachment. Trimmer is an FS-85 stihl I'm not sure who makes the attachment. Anyone have experience with a staight edger attachment on thier trimmer. Cost was $100 but it worried me that they didnt have any pictures or demo model to show me. Dealer has always been excellent towards me so they wouldnt sell me a piece of junk.
