HARFO Smart Keyless Entry Fingerprint Door Lock with Keypad & Handle - Electronic Deadbolt for Front Door Security - Perfect for Homes, Apartments & Offices (Black)

This was such a great purchase. We are just days into the installation and, so far, I am well pleased. I went back and forth over whether to replace the older keyless entry lock and door knob/handle. When I finally decided to do it- I took a chance in this and I’m quite proud. You can set the unit to automatically lock after five or 10 seconds. The unit also has a voice operation that says the action taking place (“enter code”, “door locked” or “door opened”, etc). You can set multiple entry codes, including an admin user. The remaining codes include frequent users, such as family members, and even a one-time temporary code can be set (I’m guessing if someone would like for an Amazon driver to leave a package inside your house rather than on your doorstep- though not for me). It has FOUR ways to unlock- numerical code, fingerprint (option to include as you’re setting up each user), a key card (there are three and they can be activated for anyone to use after connecting through just one user), and the old fashioned metal key backup (there is a hidden keyhole). The unit requires four AA batteries. I put in lithium batteries, hoping that they last for a bit longer. I will update this review periodically. However, I am very satisfied with this purchase thus far.1/3/23- It has been a couple of months and this high tech lock is still going strong. If for any reason the lock is unable to fully securely lock, it releases a very alerting sound that helps you know to go back to check. I have the unit set to automatically lock within 10s in case someone walks off without locking/forgets to lock. This is especially important in case kids are coming in as they can sometimes disregard the need to lock the door after entering. I think this is a thoughtful security feature programmed in the unit. There are a couple of down sides that I hope the makers will change. The first is that the voice announcement only projects outside the door and not inside. So, you cannot hear the “Door locked” confirmation or the sound alert if it doesn’t lock. The second thing is that there needs to be a sensor added so the lock will begin its timer only after the door shuts. Sometimes we are closing the door at the ninth second and the deadbolt quickly extends outward before we can fully close. This is more frustrating than anything else, but it would help the product have a more real time/customizing advantage.Final note: I chose to put lithium batteries in the unit, so I would definitely recommend this option over anything else.
