This lock is great. I really like it, and I feel secure using it — which is to say that it functions exactly as I had hoped and expected it to. The fingerprint reader reads very quickly and hasn’t rejected my print once yet. It’s built pretty sturdy, and I think it’ll last a while. It was super simple to install and just as easy to set up. It’s also easy to use and seems to be easy on batteries. I’m always hesitant to talk about battery life on something that uses batteries rather than having a battery built in, bc brand and chemical composition will make your mileage vary. But it seems to “sip” on the batteries, if you will. There’s no connectivity of this lock to your smart home, so don’t expect Alexa or Google Home to see it or “make it go”. I love my Alexa and the myriad of things I connect to her (I love IoT), but I really don’t need to verbally tell her to lock or unlock doors. Besides, to me, that’s a security risk — even in locks with the ability to do this and locks with PIN codes — if someone knows your code, they could just say it loud enough from outside for your smart home device to hear, and open right up, which might get you burglarized…or worse. Anyhow, it’s a fantastic lock, and it hasn’t failed me yet. I give it 5/5 stars.
