I have received my lock and have to say I really like the functionality and the way it works. I won’t say too much about it as that will come when we are allowed to post reviews. However, I do have concerns using this as my main lock with regards to the physical security and certifications around this, and how this affects home insurance in the UK. I have posted on the other U600 thread asking this, and hope someone from Aqara can expand on this.
