Didn't even last a full year before I started having issues with it. 1. Lock wasn't connecting even with the fact that the connect and lock are next to the router 2. Lock would flash green regularly for no reason and when I contacted support they had no idea what I was talking about 3. Almost got locked out of my house when the lock wouldn't open even with fresh batteries 4. Fresh batteries installed and lock makes sounds like it's struggling to move half an inch. Worst investment I made, and I regret not following the reviews I read online before purchasing. If you really want a smart lock then look elsewhere.
