Hot topic in the Mikey household

I can understand the interest mikey, but I have a few concerns. Is there a manual over ride so you can use it traditionally if the gadgetry fails? I am a fan of technology but do like to be able to revert to a simpler option if required. Also I'm not sure I can currently justify £4k on a toilet. Our bathroom will be getting replaced in the next couple of years but that's a healthy chunk of our budget for the entire bathroom.
