Query: Very poor construction

I was very disappointed with this towel bar. Compared to the Victorian stainless steel model that I purchased earlier, which I considered to be well manufactured this model was made cheaply. The mounting tabs that attach to the wall are very flimsly compared to the Victorian, and the mounting brackets on the towel bar did not properly align so I had to loosen a screw to rotate bracket to get the thing to line up. The bar itself is made of thinner tubing, and the stainless steel finish was tarnished.
