post is well painted, easy to lift, and of good quality. We look forward to installing. Rated 4 stars because needed additional information about the surface mount fasteners that came with the post. Instructions should indicate whether or not an on-size (10 mm) or slightly larger hole should be drilled, and also the nearest SAE equivalent size for the fasteners and for the size of the drilled holes should be provided. Thank you

Quality is good but hardware horrible
Great product, awful hardware.
While the main product quality is solid, the included M10 hardware is completely impractical for standard DIYers since finding the exact metric drill bit size is a nightmare. I had to drill out the post holes to fit 3/8" hardware instead. Good product, but prepare to supply your own hardware
