I'm serious.  This is by far the best toilet paper design I have ever seen and I can't understand why they make anything else.  How often do you find that the TP has run out and there is a new roll that no one has bothered to put on the holder.  This holder solves that problem.  Simply lift up one side and slide the roll on.  No springs, no open loop for the roll to fall off, simple, elegant, quality construction.  I am a convert.
