My wife loves this as a work of art and a butter dish. I'm a man who appreciates things, and this is indeed a beautiful object. 
As a man (also know as a slob) I have one comment. When I over-estimate the amount of butter needed, I tend to scrape off the excess, usually against the edge of the container, so as not to wast the excess.
With this beautiful item, I have had to find an alternative, as the lid fits neatly into the recess at the top of the dish. If I scrape off the excess on the edge of the dish, it welds itself onto the lid when this is replaced, so when I remove the lid the next time and put it down, there is a layer of butter around part of the lid...
