I have had the lock since Nov 2022.  Works great in fair weather, living in Canada the winter months get cold and at -15 and colder the lock pad will light up and do weird things causing the batteries to drain.  I have gone through more than 4 batteries a month since I owed it, even tried rechargeable LI-ION batteries which work but the software will not show you battery life.  says 100% all the time so I switched back to alkaline.  If you have in a heated space like apartment or condo or live in a warm client, you will probably enjoy this product more than I have.
