I purchased this bidet after a similar priced (Korean) made bidet expired before the second year was up. The BioBidet BB-1000 has better features and has already exceeded the 3 year warranty. I am now in my 4th year. The only thing I had to buy today was new deodorant and new filters. And, yes, I do recommend filters with all bidets to prolong life. The quality exceeds my expectations and I would recommend the product and would purchase again. It is a winner. . . Thank you!
