I love that the rods spin so that you can easily hang and remove the back towel and that it takes up less space than 2 individual towel bars for 2 towels.  The only draw back is that I had to order it in 24" which was too big for my wall.  But it was fairly easy to hack saw the bars tot he desired length.  I wonder why you don't offer the double bar rack in the 18" so that the hacksawing is not necessary AND I WOULDN'T BE PAYING FOR MATERIAL I DON'T NEED.!
