This is a great idea and when I first attached them to the toilets I was satisfied. However, after a month or so, the adhesive started to give and the unit began to slowly move out of place.  One of them broke shortly after and I removed the other one as soon as I realized it was following the same pattern.  The adhesive on the back of the item is not very strong, but it is strong enough to leave part of the backing stuck to your toilet!! I can't get the stuff off & now have to find something to get it to come off the rest of the way.  Not worth the money, try another style.
