Sorry that I missed this question from you.
I just saw @blancpain4470 posted U-Bolt pro then only realized your question few months ago.
FYI, I have been using UltraLoq UL1, AutoBolt and Bridge for since June 2018.
The status:
UL1:
* Still working but the lever is shaky.
I dismantled it and found it's not because of loosen screw..
Likely a mechanical design flaw and no clue to fix it.
* The fingerprint sensor requires few trials to get it through.
* Out of battery 3 times without early signal.
Otherwise, it is still usable now.
AutoBolt:
* Motor spoiled after few months.
Claimed for a replacement unit from US.
Working till now.
* Out of battery 2 times.
Bridge:
* Blew up one unit.
* Got a replacement unit and spoiled within a year. No plan to get another one.
I have another Korean's digital lock at home.
As a comparison, Ultraloq must be handled with care.
I'm going to buy new digital locks for my new house and Ultraloq is out of my consideration.
Better late than never i guess. So far so good for me
And the fingerprint sensor detection is i’d say is quite excellent. It’s probably an improvement over the older model
