I have to laugh but the amount of frustration I went through with this handle and knob. Oh my gosh. And yes I have changed multiple and installed a couple before this. First the internal screw holes for the knob itself were too large for the provided screws. The head slipped right out. Then the paper diagram was slightly off in comparison to our door. So it took taking it off and on with minor readjusting to get it right. But the worst part was that my door opens from left to right. I couldn't find anywhere in the instructions on how to switch the handle to fit. I gave up for 2 weeks. Then with fresh eyes I tried again.  And sitting fidgeting with the handle flipping it up and down realizing you could pull out the latch thing and turn it -_- Finally it is on, after considering an entire new door and 2 weeks with the handle upside down.  But it's beautiful now.
