I’ve actually purchased several handrails from Vevor and all were quick to receive, easy to assemble and install. Although they didn’t come with hardware for wood installation that was easily solved by running to the hardware store and getting 1&1/2” lag bolts. predrilling the holes so as not to split my stair treads. I have also installed 2 sets in a cut rock staircase but used Tap-Con screws instead of the drop anchors that came with them.OVERALL I would purchase handrails again from Vevor.
