After reading many reviews on here I decided to give this a shot and bought a spool. All I can say is this stuff is CRAP. I was expecting much longer run time based on what others have reported but I will tell you this is not the least bit true. I loaded my Speedfeed up with it and decided to give it a shot edging a curb that had some serious overgrowth. It literally took about 10 seconds to wear it down to the point of where I needed to feed the head. I've been using some cheap stuff that I grabbed at Home Depot and it runs circles around the Gatorline. I'm bummed as I hoped this would be much better than it was.
