I have had problems with the Style Plus leaking, from the fill valve (2x) and the vacuum break (2x). I have had the flush return spring break and the attaching point on the plastic base for the spring break snap off. Last January we replaced the Style Plus when the spring mount broke after 12 years of full time use. I replaced it with the same Style Plus from Amazon. That replacement toilet's base had cracked at the rear by late April, I replaced it as it deteriorated further and started rocking in August with a Dometic 310. No problems so far with this toilet.
