I ended up liking the unit and it fits my needs.
Pros: Price is great ($20). Fit very nicely over my toilet and it gave me ample space to store items. I like the 2 optional positions for the bottom cross-bar. The top hole did not fit because the bar lay on the water pipe. But the bottom one fit just under the pipe.
Cons: As with most other units of this kind, reviewers complain about sturdiness, especially if you don't secure to the wall, which I didn't because I rent and because the mounting hole faced the border between tile and wall. So when I stood the unit up, it did feel flimsy. What I did was stuck 2 self-adhesive pads under the two front legs. That way the unit naturally leaned against the wall. No way is it going to fall in any way unless someone pushes it. So, I'm happy with how it stands.
Also, I knocked off 1 star because the drilled holes for the bolts and screws are a little untrustworthy. I was surprised that I couldn't easily thread the bolts by hand. Had to apply pressure on some of them, to the point that the metal on the bolt head bent. I had to return one unit, which Walmart gladly and quickly replaced. The replacement unit was a lot better in that aspect. Still, be careful of the threads. Start with very little pressure and work slowly.
