I would have given 5 stars, however, since I couldn't purchase additional brackets, separately (had to purchase a 4th rail to get the brackets), I gave it 4. Delivery was quick and rails arrived with no damage. Vinyl is thick, over aluminum; very nice quality & strong/rigid. Used my miter saw to cut to size. Simple, easy instructions. Really like the color. Very nice product, replaced the rails on our porch.
