I tried out the Sling Flexible Sink Caddy on my kitchen sink.  It is pretty flexible. I had to put it over my divider in my sink. The divider, divides the two tubs.  I put a sponge on one side and my dish brush on the other with the whole in the middle.  My sinks are not that deep so the brush leans a little while in the holder.  I tried to put the caddy like one of the images on the cardboard. I guess the way my sink is made i couldn't get the flat surface to stay flat and put something on it to have it hang over the back.  It works good in the middle of my sinks until i put a lot of dishes in or need to place a cutting board on my sink.  It makes things lop sided.  Overall its a great product its just that my sink sides aren't slender enough nor is my sink deep enough.
