It was super fast and easy to put together but I found it rather flimsy and cheap feeling. The individual dividers are extremely flexible almost too much so. In my opinion they are also not tall enough. It works fine when you have enough lids stacked in each slot, but when there is only one or two they just fall over. If you over pack 1 section the divider just bends and pushes into the next section. The next version should have thicker dividers that go in slots in the bottom as well. In my opinion the whole thing needs to be about an inch and a half taller to work properly.
