Review on Favoto Disc Lock Alarm: 110 dB Sound Padlock for Motorcycles, E-Bikes, Bicycles & Scooters with Reminder Cable and Carrying Bag - Black by Anthony Woolley

I bought this mainly for the alarm feature, to create a sense of urgency to disable this and other locks and alarms or leave them alone. You have to kneel down to toggle it on and off so the thief doesn't want to be vulnerable while they work. Don't use it alone! The thief will break it simply by hacking it. Use them with U-locks, alarms, and GPS trackers to keep them occupied while approaching them from behind with a crowbar (LOL).
