I was wondering if anyone has had any experience with the INAX Dover or Saint Clair dual flush toilets since this thread was last updated on 3/8/2011? I haven't found independent reviews of either of these toilets on the internet. I was wondering how they compare with the TOTO Drake II CST454CEFG with respect to clogging, clearing skid marks, and clearing liquid? The flushing technology for these INAX and the TOTO look similar, double vortex vs double cyclone, and they all have MaP ratings of 800.
