The toilet works well.  The only complaint I have is that this toilet uses a t-nut in the closet ring so that the attaching bolts can be almost flush.  A much better look than the caps that the previous toilet used.  The problem is that there is no way to hold the t-nuts to the closet ring so they drop down into the void (unless you fill it with grout).  I ended up using the attachment t-studs from my old Kohler toilet that attach firmly to the closet ring so that you can set the toilet down with the wax ring without worrying that the attachment points are gone.  Good idea from Kohler . . . bad execution.
