Works less than 25% of the time! 
The touch part of the lock works maybe 25% of the time. There is no rhyme or reason for when it does to doesn't work.  The geofence never worked. I couldn't get the touch cards to work. Couldn't get 2nd lock to pair with Apple Homekit. 
It does work consistently via the iPhone app, but I have to open my phone, open the app, select the lock and then press & hold to unlock! It'd be easier to just use a key. 
I do like that it auto locks after a couple minutes. So there's that. 
Would not recommend.
