These bollards are a good value. They seem well constructed for a medium duty situaton like a residence. Mine have not been connected yet so I can't tell how long they'll last etc., but they are a reasonably heavy thickness of stainless steel with seamless construction. I like that the cap screws on easily and is well sealed, but will be easy to remove for changing lamps. I preferred this model with replaceable lamps to others with built-in lamps because I hate the idea of one lamp dying in 5 years and then having to replace the whole, fairly expensive, bollard. Or worse, being unable to replace with a matching one because they are out of production. It would be a big improvement if they came with low-cost, punched steel or even plastic templates matching the holes in the bottom flange so that it would be fast and easy to set 6mm stainless all-thread rod in wet concrete straight and level and properly spaced to align with the bollard. Without a template this becomes tricky, and subject to misalignment issues.
