Product review (3 stars): Overpriced ! But necessary.
This hose fits or Kenmore elite dishwasher perfectly.  It probably cost a couple bucks to make,  and the only reason you need it is because it has the 3 noon corrugated sections to snap in the holder.  You could probably make the regular drain house work that is 1/3 the cost.
I needed this because I was given a nearly new fancy dishwasher from some friends who had a rat eat this hose.  So,  for the price of this I got a nice machine working to replace my old junky one.  Very simple to install this,  took about 10 minutes and only requires pliers.  3 stars because of price.
