This is a review of the Stihl MS 500 i , after six months of commercial use. The saw was used with a Stihl 36 inch, light weight bar primarily, as well as a 32 inch Stihl light weight bar for some of the time. It pulled the 36 inch bar with no problem and it cut like crazy with a 32. There is more to say....but I suppose you will have to watch the video if you want the full scoop.
