Do not buy if you have a slanted ceiling. The product overview is misleading. It states "Sloped Ceiling Adaptable." Here is the manufacturer's response to my inquiry "We're sorry that we didn't sell this adapter, you can purchase a sloped ceiling adapter from other sellers or your local stores. Please kindly measure the diameter of chandelier's downrod, and then purchase a suitable adapter, thank you!" This is neither included nor can be found anywhere. 
It's a beautiful chandelier if installed on a flat ceiling. I wouldn't have bought it if the correct information was provided and saved the installation cost and potential removal cost.
