Best For

What Buyers Say

Users are consistently surprised by how quickly the fingerprint reader works, often unlocking in less than a second without multiple attempts. The IP67 rating seems to hold up for outdoor use, with many confirming its resilience in various weather. While the app offers extensive control like user management and unlock history, some found the initial setup cumbersome due to permission requests. The battery life is generally praised, though the need for USB-C charging if it dies is a practical consideration.

“Dude, this thing actually works! I just touch my thumb and it pops open, no fumbling with keys or codes, even when it's raining. My only gripe is if I want to kick someone off, I gotta redo everyone's print, which is kinda annoying.”

Common Praise

  • Fingerprint recognition is fast and accurate, rarely requiring multiple tries.
  • The lock feels heavy and sturdy, not cheap or lightweight, despite its appearance in pictures.
  • Battery life extends for months, reducing frequent charging needs.
  • The ability to track unlock history through the app is a useful feature.
  • Multiple unlocking methods (fingerprint, app, Apple Watch) provide flexibility.
  • The IP67 waterproof rating allows for confident outdoor deployment.

Common Complaints

  • Deleting one fingerprint requires erasing and re-registering all stored fingerprints.
  • The app asks for many permissions during initial setup, which can be a privacy concern for some.
  • Some users reported confusion with the charging port being USB-C, while older models might have used Micro USB (though this model specifies USB-C).
  • Reliance on Bluetooth means you can't unlock or manage it remotely from outside its range.

Ownership Tips

  • The lock's status light indicates battery level, which is helpful for knowing when to charge.
  • It's possible to temporarily power the lock with a portable battery pack via USB-C if it runs out of charge while locked.
  • The shackle size is accommodating for various applications, unlike some smaller padlocks.
  • The app's user management features are more robust than expected, allowing for temporary access and tracking.

Frequently Asked Questions

How many fingerprints can this lock store?

It can store up to 20 fingerprints, including two administrator fingerprints and 18 regular users.

What happens if the battery runs out?

If the battery runs out, you can connect a USB-C cable to an external power source to temporarily power the lock and unlock it.

Is this lock truly waterproof for outdoor use?

Yes, it has an IP67 waterproof rating, meaning it's protected against dust and can withstand immersion in water up to 1 meter for 30 minutes.

Can I share access with others?

Yes, the app allows you to share unlock permissions with family and friends remotely, and you can manage up to 1000 users via the app.

How long does the battery last on a single charge?

The built-in 110mAh rechargeable lithium battery can last for about 6 months on standby or provide approximately 2000 unlocks after a full charge.

Buying Guide

When you're looking at smart padlocks, you need to think about how you'll actually use it. Is it for your gym bag, a shed, or a gate? The unlocking method is key – fingerprint is fast, but app control gives you more features like tracking. Also, consider if it needs to survive rain or dust, so check that IP rating. Battery life is a big deal; you don't want to charge it every week.
