My boyfriend bought this for our home a few weeks ago. It didn't take long to set up, thankfully. Once it was set up we quickly found out we cannot manually lock and unlock the door because it screws up the Sync between Alex , Our phone and the lock. Even if we lock and unlock the door from the app we set the app up so that the door will unlock when we walk up to the door and more often than not my phone/app doesn't end up communicating with the lock and I have to put down all of my things, take my phone or keys out of my purse and unlock my door. It completely defeats the purpose of being able to have my hands full and just walk in. Definitely frustrating. Needs improvement
