1 charge is equivalent to a year? Who would choose to lock their houses for a year? haha

Pros: 

* IOT bad-ass padlock. Couldn't be as automated as regular solenoid locks and knobs.
* Both can be used for traditional keys and modern authentication system like fingerprints.
* Its design is same as the regular padlock which is good for me. No one will ever be curious about it

But I saw some Cons for this
Cons:

* Fingerprints can be copied. It's susceptible to glitches especially it's electronically driven.
* No extra securities like what if someone wants to smash it or hit by a hammer. Nothing is hard with the bolt-cutter, ya know!
