Great thread, probably a good buy if you regularly make a mess of yourself and the big roll can’t cope! Personally I’d opt for a pack of wet wipes next to the pan for emergencies or to treat yourself!
I went for an interview with a company in London who had one of those spaceship toilets, most disappointing thing about not getting the job was that I wouldn’t be able to use it on a regular basis!
Ps. Only time I ever used a bidet was on a hockey tour in Italy when after several brews I took a dump in it luckily it was in someone else’s room!
