I am baffled by your limitiation in the Latch locks of a max of 50 codes users. I migrated all of my locks with the exception of a few over because we as a small business have quite a large driving force. you make a better and more sturdy hardware platform and then cheap out on the number of codes(users) you will support. Your competitor (Sifely) makes a doorlock that is nowhere near as stout and sturdy as yours but i have over 146 codes and counting on those locks. If you want air to be business friendly and compete then open up and drastically support more users and codes on each lock. So sad!
