I bought 3 of these a few years ago and they’ve worked perfectly.  It was very easy to have them set to the same key.  Fast forward to today when I accidentally broke off a different key in the knob.  Although I wasn’t able to get the broken piece out and had to buy a new knob set, I’m still super satisfied because of how easy it was to set the new lock to the existing key and re-install the new one on the door.
