The design of this hose has recently been updated and it no longer fits with the companion Kohler slide bars.  The shape of the nozzles at the end of the hose have been changed from what's shown in Kohler's product photos.  With the updated nozzles, the hose doesn't sit securely in the bracket on Kohler's slide bar.  The hand shower wobbles back and forth and doesn't stand vertically.  It's functional, but doesn't really work optimally.  Avoid if you care about details.
