I hate them. The only bathroom on the floor has these machines from hell and when they flush they are as loud as jet aircraft. The problem is, motion sensors don't do a good job of detecting when I'm done and ready to flush. As soon as I sit up--FLUSH. Without going into too much detail, the toilet paper is so low you have to sit back down again to get it. I think that stupid thing flushed 3 times. lol I'm going to introduce legislation to ban them. Who is with me?
