Well, it’s a great idea, if you have little feet  or wear only sandals, flip flops or tennis shoes. Otherwise, you‘lol never fit 18 pairs in it. It wasn’t too hard to put together. I bought two, one for a gift, but that family have bigger shoes than I have. Alas. 
If you have lots of little feet in your home, this is perfect. I’d put it near the entrance so everyone can take off their shoes when they walk in the door.
