I did ... I was on my way to the supermarket when off to the the right was a guy in his front yard using a Stihl FS 90R. I slammed on the brakes to make a sharp right turn and pulled up in front of the guys house real quick. The look on the guy's face was priceless, and then when I said I stopped there just look at his string trimmer, I could tell he thought I was NUTZ!! I started asking him a bunch of questions, but he said he just bought the string trimmer an hour ago and was using it for the first time before I showed up. It sounds great - doesn't have the high pitched scream of a 2-cycle.
