Simple description
1. HW is quality.  Installation is easy
2. Apple Watch app never works. Never Never Never
3. Geofencing , auto-unlock feature works 75% of the time
4. I have tried to be supportive and initially worked with them to file tickets, but they gave the same response and never resulted in anything.
5.  battery draw on the Pro lock is excessive. 
6. Manual unlocking the lock with the iphone app is super slow.
