This is the first time I have ever replaced a door handle but I was able to figure it out after watching a couple of YouTube videos.  The instructions didn’t do a good job explaining how to do it.  However, the reason I gave a 1 is that the bottom hole didn’t line up with my existing hole.  There is a removable bottom plate that has 3 hole options and my existing hole fell between the bottom two.  No matter how much I tweaked it I could not get the handle in the existing hole.  I ended up having to drill a new hole and now I have to figure out how to patch my door—very upset about this.  The attached photo shows pencil marks where the bottom 2 hole options and I drilled a new hole for the top hole option.  This problem could be easily remedied by re-engineering the removable plate so it’s adjustable.  Rather than a circular hole for the 2 screws (circled in green in photo), it could be a rounded rectangular so the plate could be adjusted up or down.
