It was easy to setup. However, due the shape of the hooks, it does not fit hang properly from the existing rod.  The existing rod is wood and 3 inch in diameter.  The hook on the closet rod is not circular or large enough to hang completely.  I had to force the hook on to the existing rod.  I am currently using the closet rod to hold my dress shirts and pants.  I do not want to put a lot of weight on the rod since I do not have a true rod to rod connection.  Wish there was an up close picture of the rod hook on the website page of the item or made the hook to be round/circular to fit any rod type.
