I had a very old one over 10 years old so they do last quite a while. I love the new design and the push button. So much easier and it sits up higher than my last one. Installation was easy- I did have a plumber doing work who di it in about 10 minutes but me might have been a bit longer. It is much more streamlined and looks great. I have been and continued to be happy this is my third one and they really last a long time!
