An excellent lock from a name I trust. It's not laden with features (it is, after all, only a padlock), but it is a solid performer. Works as advertised, has no problems functioning in a steamy gym locker room environment. Unfortunately, I pretty much use this padlock exclusively in Locker mode since I have it on my gym locker. That means I am always entering the code on the dial instead of benefiting from the Bluetooth proximity activation feature (since my phone is always in my locker when I use this lock). That said, it does it's job well and has given me no problems or issues at all.
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.
