One small bug: if you close and then quickly open the lock again before the lock's mechanism clicks, it will remain unlocked. Even if you close it, it will still be openable. The only way to make it lock properly again is to enter the code on the front of the lock (like you are unlocking it), and let the lock unlock. Then lock it again and do not attempt to open it until after the mechanism clicks. I can repeat this behavior, so it does seem to be some kind of bug, but at least it is easy to resolve without any complex steps to follow.
I returned it and bought this instead. App is great and it worked the 1st time. I use it in my gym locker and luggage.
To be fair, it has been a great daily bike lock, but for high traffic areas where people can touch it...I would try a different options.
If masterlock does write back to fix the issue, I will update this pose. Till then...buyer beware and don't go to beta swipe.
