Review: Risers are solid and look great - The risers themselves are pretty tough. Mine arrived with some of the mounts bent and I had to hammer them back straight, but it didn't take much powder coat off. I used my own hardware, so I can't speak for that portion. I haven't noticed any flexing when using the steps, so they're nice and rigid. They've been installed for about 2.5 years now and still look great. I will say the step angle is kinda shallow and awkward, but I did use 2×10's as my runners, which fit great, I must say.
Review: Great for extending stairs - We needed to extend the stair stringers on the stairs to our pier by one step - these were perfect for that purpose. They are well made and heavy duty.
