I bought the WC Exclusive miracle a few months ago. You had to get used to the handling, in order to use them properly. So also for guests rather unsuitable. Under abusive conditions may accidentally a whole barrage toilet water "out shoveled" are ... After some time I noticed that despite cleaning with hot water brown spots stick to the pad. Since I did not want to edit with the sponge, I would rather buy the replacement pads. At the last minute I read the small print that they do not fit on the exclusive variant. I have contacted the manufacturer, to no avail ... I assume that one (which incidentally also looks only at first glance better, it's just all plastic ....) in the exclusive variant, the pads do not can replace. My toilet wonders for a total of 40 has finally landed after 5Monaten in the dustbin.
