AI Verdict
This is a Bluetooth-connected, biometric padlock with 0.5-second fingerprint unlock and app control, suitable for basic security where keyless access is a priority.
This padlock is a situational fit for users prioritizing keyless access and basic security with its 0.5-second fingerprint unlock and Bluetooth app control. Its Zink alloy and stainless steel construction offers some durability, but the lack of an IP rating limits its suitability for outdoor or harsh environments.
If you need robust outdoor use, look for a smart padlock with an IP67 or IP68 weather resistance rating and a larger battery capacity.

Cons

Dimension Scores
The lock boasts a 0.5-second fingerprint unlock speed and a 99% recognition rate, which is quick and reliable for a budget biometric lock.
It uses Bluetooth for app unlock and control, which provides convenient local access but limits the range to within close proximity of the lock.
The app allows for administrator and user setup, remote unlocking via Bluetooth, temporary password generation, and unlock time recording, offering a decent set of smart features.
Constructed from Zink alloy and stainless steel, it feels sturdy, but the absence of an official IP rating means its resistance to water and dust is unconfirmed for outdoor use.
Best For
- Gym lockers where forgetting keys or combinations is a concern
- Toolboxes or cabinets needing quick, keyless access
- Indoor storage units requiring shared access management via app
- Situations where a physical key is inconvenient or easily lost
Not Recommended For
- Outdoor gates or sheds exposed to harsh weather conditions
- High-security applications requiring advanced encryption or tamper detection
- Users who prefer not to rely on a smartphone app for lock management
- Locations where Bluetooth signal might be unreliable or unavailable
Watch Out For
- No specific IP rating means potential damage from rain or dust is a risk, despite one user claiming it's waterproof
- The 110MAH battery, while offering long standby, will eventually require charging, potentially leaving the lock inaccessible if not monitored
- The lock starts in a factory mode where any fingerprint can open it, requiring immediate setup to secure it
- Bluetooth range limitations mean you need to be physically close to the lock for app control and remote unlocking

What Buyers Say
Most initial impressions from reviewers highlight the straightforward setup process and the convenience of both fingerprint and app unlocking. Users appreciate not needing to carry keys or remember combinations, especially for gym lockers. The lock's ability to store multiple fingerprints and track unlock history through the app is also a frequently mentioned benefit. However, the lack of a clear weather resistance rating is a recurring concern for potential outdoor applications, despite some claims of it being waterproof.
“Ugh, another smart lock that says 'waterproof' but doesn't actually have an IP rating, so I'm not risking my outdoor shed with this thing, but it's fine for my gym bag.”
Common Praise
- Fingerprint unlocks in less than a second, making access quick
- Setup is easy with clear instructions in the manual
- App allows for managing multiple user fingerprints and viewing unlock records
- USB rechargeable battery offers a long standby time of up to a year
- The Zink alloy and stainless steel construction feels durable
Common Complaints
- No official IP rating, so actual water or dust resistance is unknown
- Bluetooth range is limited, requiring close proximity for app control
- The lock ships in a mode where any fingerprint can open it until configured, which is a security risk if not set up immediately
- Battery level indicator uses 4 lights, which isn't as precise as a percentage
Ownership Tips
- The silicone cover for the USB charging port is essential for protecting it from dust and moisture
- Regularly checking the battery indicator lights is crucial to avoid being locked out
- The app's interface for managing fingerprints and history is intuitive after initial setup
- Bluetooth connection can sometimes be finicky, requiring a few attempts to connect to the app
Frequently Asked Questions
How do I set up the fingerprint recognition?
You'll need to download the companion app and connect via Bluetooth. The app guides you through registering up to 15 fingerprints, including the administrator's, and managing other users. The lock is in factory mode initially, meaning any fingerprint will open it until you set it up.
What happens if the battery dies?
The lock is USB rechargeable, so you can connect it to a power bank or charger using a USB cable to power it up. There are indicator lights to show the battery level, with 4 lights indicating 100% charge.
Is this padlock waterproof for outdoor use?
The product specifications do not list an IP rating for water resistance. While one user mentioned it being waterproof, the official specs only state Zink alloy and stainless steel construction, so it's not explicitly designed for prolonged outdoor exposure to rain or harsh weather.
Can I share access with others?
Yes, through the Bluetooth app, you can add up to 15 fingerprints for different users. The app also allows you to generate temporary passwords and view unlock time records.
How long does the battery last?
The 110MAH lithium battery is rated for up to 1 year of standby time or over 2000 unlocks on a single charge.
Buying Guide
When you're looking at smart padlocks, you need to think about how you'll actually use it. Do you need it for a gym locker, a toolbox, or something outside? The unlocking method (fingerprint, app, temporary code) and how tough it is against weather are the big deals. Don't just assume 'smart' means 'indestructible' or 'weatherproof.'
Connectivity (Bluetooth)
This tells you how the lock talks to your phone. Bluetooth means you need to be pretty close to the lock for the app to work, like within a few feet. It's not like Wi-Fi where you can unlock it from across town.
Lock Type (Biometric)
Biometric usually means fingerprint. It's super fast and convenient because your finger is always with you. But make sure it can store enough fingerprints for everyone who needs access, and that it's accurate.
Material (Zink alloy, Stainless Steel)
This is about how tough the lock is. Zink alloy and stainless steel sound strong, but for a padlock, you also want to know if it can handle being cut or if it will rust. It's the physical protection against someone trying to break it.
USB Rechargeable
This means it has a built-in battery you charge, like your phone. You won't be buying disposable batteries, which is nice. But you need to remember to charge it, or you might find yourself locked out when the battery dies.
Alternatives
If this lock doesn't cut it, look for models with an IP67 or IP68 rating for guaranteed weather resistance, or Wi-Fi connectivity if you need truly remote access and control.
