Review on Kohler Brevia 20111 White Toilet by Jason Pinkney

Seat works as described. Installation images are on the packaging, but they refer to seats with the quick release feature, which is not available on this model. Quick-release fasteners are no faster than any other toilet seat. Plastic wing nuts must be supported from below when screwing from above, otherwise they will turn with the screws and will not be tight. The center hole of the metal washers is too big for these screws, so they may slip when tightened.
