I rarely write product reviews. I originally ordered this product for a new flower bed. Since then I have re-orded 4 more times, replacing some other flower bed liners. Why? This product is heavy-duty, does deep into the ground, looks great, and is just flexible enough to follow the desired shape of the beds. Once in, no grass is going to grow under it or through it. It even comes with heavy duty cover pieces to cover the seams between any two pieces. It was a little difficult for me to install, only because my yard has a rocky soil and I had to remove rocks that got in they way. I installed mine so that it is just low enough I can put one side of the lawnmower over it and cut the grass right up to the liner. I 100% recommend this. It also looks great!
