For sale: a ryobi string trimmer 18v with NO battery included. Its a very basic trimmer for small yards. I bought it a couple years ago, I use it a handful of times each year. No issues, runs fine, just pretty weak and the line feed is annoying for all the area I trim. I decided to upgrade my string trimmer to a more powerful one. May be fine for you if you have a small yard and don't trim much. I believe the website below is the same or very similar model.
