I first purchased a BB-2000 in 2016 after my son purchased one and I just had to have one of my own.  I had debated rather to get another one for one of my other bathrooms but was on the fence for several years.  But then my son called BioBedet support for his seat, and they sent the parts at no cost, even though it was well past the 3 year warranty.   It was not that much money for the parts that was just "given" to us by BioBedet, but the fact that they helped so quickly, at no cost, after so many years was very nice.  We got the parts within a short period of time and fixed the seat within mins.   I was so impressed with Bio-Bedet support that I got online and ordered my second seat.   My new seat arrived in short order and I had it installed within 15 mins.   I am in heaven :-)
