Query: LIGHTWEIGHT AND SAFE

I bought this to replace a cement bird bath which came in 2 separate pieces. What I found is that the cement one posed a danger to kids and anyone else who touched it. This unit is short, lightweight and safe. It's easily filled with stones or water before attaching the top with three included screws. It's nice looking, and not a safety concern.
