Sturdy, easy to put on and take off and lightweight. Easy enough to find out. The system clearly didnt work and we decided to return it. I had trouble getting my iPhone to charge; sometimes it would sit on the cradle for 90 minutes and charge right up, other times it would sit on the cradle all night long and not charge at all. The sound effect is so good, out of my expetation. Absolutely love this shoe rack. Design/Features:Not much to say in this department. l box to cover the product when it is delivered. I was able to close the second row of hooks quite easily, so I should have sized down to the XL. Multiple door pieces broken.
