Query: Unstable rack

Although the shoe rack fits the space I had for it well and serves it's purpose, it is poorly made and doesn't hold together very well. The poles are hard to fit into the plastic end-pieces and often fall out, causing one or more shelves to collapse. I ended up duct-taping all the poles into their sockets, which helped some, but if any one slips out the whole thing will come apart. You also have to really pound the poles into the end-pieces to get them to be equal lengths, or the whole shelf wobbles. If you want a quick, cheap shoe solution, this probably will work, but you'll have to keep putting it back together and it won't last very long.
