The lights look great, however I don’t think the average person would find the installation very straight forward. The flush mount mounting bracket should have included nuts to go with the machine screws for installation. I added my own which made it better. The chandelier install requires a lot of muscle to open and close the chain links a couple of times. The wires are not labeled Hot and Neutral or coloured differently  to tell them apart - they are described and Smooth and Rigid in the instructions. If you don’t have sensitive finger tips you won’t feel the subtle difference between them. 
But, once installed the fixtures look really good. More manufacturers should make fixtures that are multi-mount.
