I was struggling on if I should give it a 3 or a 4. They are super easy to use. Do not detract from the landscape. And look halfway decent up close. But if you have rocky soil it’s likely going to be a challenge to make them look even or get them in without bending. I’m using them to keep my kids soccer balls out of a few areas when they kick from far away and it rolls slowly into a garden. Does it work Yes. Will it work for more than 2-3 years Im not sure honestly. I’m hopeful. Sure beats paying for the thick ones that ruin my “look” in the garden.
