Read the directions! Like really read them. I half read them and got to work.. then realized I needed an additional line to do what I wanted. I rented a little edger for the day and installed this pretty easy. Definitely a time consuming task - I thought it would only take a couple hours, but I was wrong. Took my husband and I all day working together. We weren’t always on task, but plan on it taking most of the day if you’ll be using the entire spool. Again, I can’t stress enough read the manual before digging.After it was installed, my dog got it right away. He’s got himself a couple times but mostly stays within the fence. I can let him have his freedom and he loves it!
