We have had the Caroma dual-flush toilet since our bathroom remodel in 2003. My first impression was similar to all the negatives posted here. I even posted a review, but it looks like the older ones are no longer online. However, after having this toilet for 11 years I need to correct the record. This is a
fabulous toilet. In 11 years we have done
absolutely nothing in the way of repairs. It has served our family of 4 with no service and never a clog. Yes, it is miserly with water. This is a very good thing, especially when you are on a pricey water system that charges by volume. And yes, the drop zone is small, but you learn to scoot forward a little and voila, success. All it takes is a little target practice.
In the meantime this toilet has saved us a lot of money in both repairs and water bills. We have no staining whatsoever. The bowl looks like new. I have a friend that installed a high-end Toto a year before ours. It has been repaired twice and the seat needed replacement. We have spent nothing on the Caroma and it continues to perform well. Good job Caroma!
