Love it!!! Heavy duty solid with draining hole. 
It does come in gray steel, give it time it will chg for you. As far as the water hole. The trick..don’t screw it down all the way, leave a slight airway. We live on the top of a hill and it’s windy all year. They’ve not budged. 
I’ve also been known to use wine corks as it is a natural way to absorb. I’ve filled mine with perennial plants with a few annuals, that’s how sturdy this are. 
5 stars. Highly recommend. Patience is a virtue, not a given. Learn to be still. Allow the copper to form. Quite interesting.
