The problem is that a low-flush toilet that works has only recently been invented. Of all six North American brand low-flush toilets sold up to about a year and a half ago, none worked well. I had one and my procedure was to flush before use to wet the bowl, flush after use to remove most of the waste, clean above the water line with wet toilet paper, flush to remove the remaininbg waste, and maybe still have to flush once more.... not much on water savings and certainly a pain in the arse (I know, I know).

I recently replaced it with a man's toilet. A Gerber 3.5 gpf, 17.5" high at the rim, with elongated bowl. Large water surface. No cold contact with any part of the anatomy not used for sitting. One flush per use, period. Compared to a low-flush, it's a pleasure to start the day.
