Query: Leaning Tower of Pisa - JUNK!

Unfortunately, my experience is the opposite of the other (positive) reviewers. What a pile of junk. The rack had several holes that were not drilled to match precisely and when I did wiggle everything to get it to jam together, one of the holes was off by 1/8". I had to re-drill.I do fine woodworking and some metal work, so I have experience, tools, and the ability to measure and assemble. But after three bolts stripped out (when I was getting them finger-tight) and the final result was a rack that leaned 15 degrees from plumb, I decided to throw in the towel.I had high hopes for this bike rack, but in the end found it to be a waste of time, money, space and effort. There is no way I would risk my expensive bikes on this teetering, wobbly, tilting mess.
