Extremely easy to put together, looks great and so far works well. My problem was using all the tiers it was too long, but removing one section of tubing made it to too short to reach from floor to ceiling. So, as previously reviewed, you may need to cut off a portion of one tube. I tried to use a pipe cutter so it would be a perfect circular cut but this didn't work well; it made a nice pattern for using a hacksaw next but material was too "soft" for the pipe cutter. Once you cut the tube, it deforms the shape (out of round) making it difficult to slip another section of tubing into the cut one. Easy fix - use the cut tubing for your base section. This will easily fit into the rubber footprint that protects your floor. I don't know how well the tubing will hold up to rust. A few reviews state a horrible rust problem, while most reviews seem fine. It may be a quality control issue at the factory where a few lemons get through. I live in Florida where it is claimed we have the hardest water in the U.S. so if this is prone to rusting, it will happen here. Time will tell as even tools hanging in my dry garage or shed will rust on the wall due to humidity and water hardness. This product is a nice set-up for the shower so if I do encounter severe rusting, I will try a layer of Rustoleum paint on the next one.
