Disasterous. Chose a product that Rizwan had not worked with; the installation was unsatisfactory. A re-visit by installer made matters worse a he tightened and stapled at random creating more buckles in the carpet. Since then seams are widening and a visible tear has appeared. A solution to the problem such as a redo was not on the table. I received a couple of hundred dollars on a $3000. installation. I do not love my stairs. I will have to have the work redone by a professional.
