caroma toilets

Just wondering if with these low bowl water level toilets are there any problems with skid marks? responses greatly appreciated.

I have a Caroma and I am happy with its performance. Yes, there have been a few times that there have been skid marks above the water line that weren't flushed away. But it hasn't been an annoyance to me.

It flushes very well. I have clogged it, but that has been only about 3 times in 2 years.
