I remember all too well the nightmare having to change out the toilet paper rolls in the bathroom, the spring-loaded double posted toilet paper roll holders were anything but easy to handle. I'm still not quite sure why those things still exist because the single post toilet paper roll holders are soooo awesome! It really is that easy to use and the design is flawless. The little lip at the edge of the single post holders keep the toilet roll from falling off the post and the design is so simple it's almost as if the holder isn't there at all.
