This was the second rack I ordered for one sink, as I expected this size to be too big, and ordered a smaller one first.  But this size was perfect!  The feet allow it to sit up a little bit from the very bottom of the sink.  I thought I needed a 27" length at the most, but with the feet, 27.5" is just right.  Seems to be made of quality materials, and I expect it to last a long time.  I imagine we'll have to scrub out the feet, which allow small food particles to sit in around the rubber, but that's okay.
