The wine rack came with one of arms bent and not welded properly.  We did not notice this until it was being put together so continued assembling it in hopes it would not affect anything. As a result, the glass does not rest properly on the bars, so we had to set something on top to disguise the problem.  We probably should have returned it, but that meant even more work taking it all apart and repacking it so we will make it work as is.
