I'm glad they sent two.  The reset button stuck up on the first one when I was setting the code.  After I did my code I jumbled the numbers to hide the code, a second later something clicked.  I went back to open it using my code and of course it didn't open, it had taken my jumbled numbers as the code because the reset button dropped down after the jumble.  Figures that I didn't take note of where those numbers were since I didn't know what happened.  I learned my lesson and was much more careful with the second one!  And it wasn't operating error by me. On the second one as soon as I released the reset button it dropped down and recorded my code correctly.
Other than that I really like the look and how sturdy the lock is!
