Very handsome, modern and durable
These are very handsome and appear to be quite durable. I am very pleased. They are not concrete, but you don't really want concrete. They are instead a very strong weather-proof plastic (acrylic?) that looks like concrete. It  is a superior choice to concrete because it is lighter weight (although clearly very durable), and not subject to cracking and staining as concrete is. The installation onto a post was very easy. The metal screw covers work perfectly; the screw hides underneath and the cap screws right on top. I have not had this up on my property long enough to know how it winters, but it certainly is very handsome. The seller was extremely easy to work with.  While we had no problems, we also had some ideas of custom work we wanted, and he was very responsive, very fair and reasonable, and was a pleasure to work with.
