AI Verdict
This Bluetooth-only smart deadbolt offers 0.3-second fingerprint unlock and multiple entry methods, best for local access or with an optional Wi-Fi gateway.
This lock is a strong choice if you primarily need local keyless entry via fingerprint or code and don't mind purchasing an optional Wi-Fi gateway for remote access and smart home integration. Its 0.3-second fingerprint unlock and multiple entry methods offer convenience, but the lack of built-in Wi-Fi limits its 'smart' capabilities out of the box.
If you need integrated Wi-Fi for remote control and voice assistant compatibility without an extra purchase, look for smart locks that explicitly list built-in Wi-Fi as a core connectivity feature.

It offers Bluetooth for local app control, but Wi-Fi and remote access require an optional, separate gateway, limiting its out-of-the-box range.

What Buyers Say
The biggest takeaway is that while this lock offers a ton of ways to get in, you're really only getting full 'smart' functionality if you shell out for the separate Wi-Fi gateway. People are stoked about the fingerprint reader, saying it's super fast, like under a second to unlock. Installation seems like a breeze for most, which is a relief if you're not handy. But don't forget to grab some AA batteries, because they aren't included.
“Dude, this fingerprint thing is a game-changer, I just walk up and it's open, but seriously, why isn't the Wi-Fi built-in, I gotta buy another box for Alexa?”

Buying Guide
When you're looking at smart door locks, you need to figure out how 'smart' you actually need it to be. Many locks, like this one, use Bluetooth for local control, meaning you can manage it from your phone when you're close by. If you want to unlock your door from work or have it talk to Alexa, you'll often need an extra piece of hardware called a gateway, which connects the lock to your home Wi-Fi. Also, check the power source – most run on batteries, so factor in replacements.
