ABUSfolding lock BORDO One 6500A - Smart bike lock with alarm - keyless opening via smartphone and smartwatch - incl. holder - security level 15

I have mixed feelings about this lock - on one hand, it has all the features I want in a lock (Gold rated, sturdy, has an alarm that's loud enough to draw attention and not too sensitive that it's triggered accidentally - a firm knock to the chain is required to set it off). The app has a map that (if 5 ft away) can tell you the status of the lock, and records the last known location (but is only live if you're within 5 ft of the lock, so not useful if you're further away and wanting to make sure the bike is still there). The lock is pretty heavy - heavier than my diamond D lock - but the attachment to mount it on the bike is sturdy. The battery lasts a while - I use it 1-2 times a week and haven't needed to charge since I purchased it last October.The main issue as could be predicted is with the Bluetooth / app - the bluetooth is temperamental at best. I've often had to restart the app several times to connect to the lock when standing next to it, and frequently the bluetooth has disconnected before the lock has unlocked and ultimately taken several restarts 10+ minutes and a lot of panic to unlock (not sure what I'd be able to do if I was unable to unlock). A couple of times I'd set out not knowing that the app had updated, and then been unable to use the lock without the activation card. About 50% of the times I lock it (and the app confirms it's locked), the lock hasn't engaged. The alarm does set in these instances. I will say that it has been a bit more reliable since the main app closed and was consolidated, if it's now very slow to connect.Ultimately, when it works it provides a great peace of mind, but there is so much uncertainty around locking/unlocking it that I keep forgetting to take it off the bike and use it only to avoid carrying it around with me. I consider it more of a deterrent than a security measure

Like how it can rest Its it's weight on other objects apart from the bike and really easy to pack and can go round both wheel and frame and object very happy with the lockjust one con which means it can weigh a lot as with any strong lock

One of the best on market.
