This is a very pretty chandelier. It is perfect for my small formal dining room (10 x 11.) The crystals weren't very difficult to attach. It was a little time consuming as others have mentioned. It took me about an hour or so to complete by myself. I do recommend having needle nose pliers on hand. I had to bend some of the metal openings to accommodate the base of the crystals. I also recommend placing the chandelier on the cardboard ring that is part of the packaging. It will keep the chandelier elevated so you can attach the lower crystals and will also allow you to keep it suspended upright until it's time to hang. I hired an electrician, so I cannot comment on the difficulty or ease of hanging. The crystals are glass. I had 9 additional crystals left over as well as several pins, so know that extras are included.
Because of the un-imposing size it is a very cute unusual fixture for a small area. I live in a log home and took the "twig" theme to the next level by spray painting nice shaped dogwood twigs black and attaching to the ceiling around the ceiling attachment portion to create a larger statement over the dining room table. Very cool. Easy but time consuming to attach crystals. Worth it.
