We bought a 4 yr old home 3 years ago with cheap Briggs low line toilets already installed since new. My wife and I always believe in buying the best products that suit our needs, not always the most expensive! After 3 weeks no plunger use on our 2 new toilets. Before that we needed to use the plunger at least once a week in each bathroom. No build up now in the bowl or rim. The silver embeded bowl and the 1 piece design are great and fit over our old floor foot print perfectly. We did need to replace our water lines (very easy). This model is a great choice. We bought them at [...]for a great price..
