I am very pleased with this product and with the Rockledge Service I used to install it (through Wayfair).  It will fit 24 pairs of flats (size 10 womens), but less if you mix in tennis shoes or heels. Some shoes had to be put in at an angle since they are size 10. I worked it out and am ordering at least one more.
