Query: It's not rocket science.

I'd return this paper towel holder if it were worth the time and effort, but it's not. You'd think assembly wouldn't be complicated. It's a paper towel holder for pete's sake. But the quality is shoddy, and the design is somewhat nonsensical. Paper towels easily fit through the center rod without removing anything. Great! So why, then, make the middle rod three separate pieces that need to be screwed together, as opposed to just one piece? Not so great. And upon screwing the middle rod to the base, the bottom of the base fell off. Because this is sold by Target, there's tax and shipping. So for about the same amount (maybe less), you can get a better made paper towel holder from Bed, Bath, & Beyond.
