We've only had it for a few months, but everyone in our home is loving this seat. Our Toto had gotten clogged from hard water, but we are able to use a filter with the BioBidet. Highlight is that it has the strongest spray. There is a power setting that truly helps with your sluggish times . I didn't believe it could work but believe it! The blue nightlight is really helpful, wish we could change the color but that is such a minor thing. They really need to CORRECT THE WRONG INSTRUCTIONS, the diagram of the mounting bracket shows it backwards with the gaskets upside down. SO annoying! There instructions and generally unclear, they need more descriptive words and correct diagrams. Use youtube to install and save yourself a lot of hassle and redo. All in all, I chose this seat carefully and am very pleased with it functionality, highly recommend
