This product can work well but needs manipulating before use. The plastic is slightly brittle so has to be heated before use,I left it in the sun for a couple of hours before using which seemed to work well but have read reviews where people have also heated in it water.
Once warmed up the product is flexible enough and works well and will firmly stay in place with place well the pins provided. I used it as a border for a gravel footpath and so far it has worked well. please be aware that in most cases it will need to be channelled intonations the ground so that it can be level.
