While time consuming to assemble, it was straightforward and easy to do. It probably took a little more than 90 minutes to attach all the crystals (while I watched tv). I used little jewelry pliers but my husband helped out on the top part just using his fingers and didnt have a problem. He installed it in our dining room quickly and easily. Now that it is done, I really love how it looks. The crystals catch the light and (while I am currently short a bulb), it gives off a lot of light. Im so happy with this purchase.
