Best on the market.
I've tried several foot scrubbers and this is by far the easiest to use and does a great job.  Being able to stand on one side as you scrub the opposing foot, and vice versa, is an ideal way to keep scrubber steady.  Ones that only have suction cups on the bottom always come loose when least expected, at least that's been my experience.  And being able to get the nice beige/brown color is great--matches my shower tiles. I have this model in two other showers as well.
