This product is excellent for retaining small rock on a slope. I use it to retain soil & rock on the sides of a 6ft round, 3ft high mound planting bed. It turned out great and I hope the picture uploads... Because I was using it on a much smaller scale than product was intended for, I did not fully expand the sells and only needed 5 rows of cells, I had to do some cutting & patch in a section where there were no holes for the included connectors. To do the patching in and to set the shape of each cell in the grid, I used heavy duty landscape staples and set them at an angle where the cell walls cross, to patch in, I made sure there was an entire cell overlapping at each end and set the staples to catch a cell wall for each of the 5 rows of overlapping ends on each side of the patch-in. I highly recommend this product for any type of rock or terraced landscaping that you don't want shifting out of place.
