It' s a working Chinese shop that lacks to fine tune the details. Personally, I recommend it for less exposed places such as warehouses or server rooms in offices, or hotel rooms that are not publicly accessible, because the lock is not that strong. I dare say that it can be broken even with bare hands. The lock only blocks the tongue of the handle, I personally would not buy it for the entrance door of the house, on the one hand, the supplied insert with the keys does not fit correctly on each door (on one side it is drowned, on the other it protrudes a lot), and then the functioning! The number pad is nice, but since it' s not in your line of sight, an inexperienced person will never hit it the first time. After entering the wrong code for the third time, the lock beeps (loudly for about a minute or two) and there is no way to turn it off, neither during the beep nor anywhere in the app' s settings! At night in an apartment building full of people, or when your child is sleeping, you really don' t want that. In addition, the codes " expire" with strange rules - if no one taps it during the first 24 hours during the validity period, it is automatically blocked. For Airbnb, this lock is hell, I only use it with the supplied chips, which are three and which can be blocked/unblocked at will and remotely. I haven' t tried the fingerprint yet. But I appreciate the possibility to share the lock settings in the app for several " admins", i. e. whatever you set can be seen by others immediately. The setting options are nice, time-limited codes, code lengths, cards, imprints, mobile opening option, remote opening (only with GW), opening records (and hoot! ). Overall, I rate the lock as a toy that can make life easier, but which is not suitable for " professional" use.
