The seat LOOKS sleek and the form function is simple and easy to operate.  The install was a breeze.  It works well and comes with 2 additional nozzles, the choice of which one to use would be a matter of personal preference and water pressure.  I gave it 3 stars and not more because the bracket mount does not hold the seat firmly and allows for the seat to shift laterally a bit, but also because the entire unit does not seem very sturdy.  If Kohler would somehow upgrade the bracket to hold the seat steady I'd add a star. And if this seat is still working and not cracked or leaking in a year from now, I'll add a 5th star.
