Fingerprint Lock Smart Padlock Waterproof

Good

Works well. Easy to setup

It works well, in fact I recommend it, but I do not recommend using it in the pool, as it does not detect the fingerprint due to the skin fold caused by water.

Good project, fast service

This fingerprint-enabled Nanjing lock is slightly more luxurious in construction compared to the regular key type Nanjing locks, and the thickness of the metal part is also thinner. However, it has sufficient performance for everyday light use. What is particularly noteworthy is the gimmick, which allows unlocking with one's own fingerprint without using a key. This is very unique and attractive. It's also very easy to use, and by scanning the QR code, you can check the setup and registration process in an easy-to-understand video, making it suitable for first-time users of this type of smart lock.

Fingerprint registration is smooth and can be easily completed by touching the same finger several times. The lock response speed is faster than expected, and when you touch your finger, the lock is released in an instant, so there's no need to search for the key, which is very convenient. However, in terms of sturdiness, it feels somewhat insecure compared to the heavy-duty南京锁， so I think it is more suitable for simple uses such as lockers, carry bags, and toolboxes, rather than high-security purposes like storing valuable items.

Regarding the battery, it is USB rechargeable, and there is no need to charge it frequently. It can be used for several weeks to months. If you are worried about the battery running out, as long as you charge it regularly, there shouldn't be any problems. The price is also quite reasonable, and it seems good as a gift for someone who likes small gadgets.

Overall, I think it's a smart lock with fingerprint authentication that is perfect for light use. The design is simple and stylish, so it doesn't feel out of place when carried around, and it's a useful item for small occasions.
