Oxford Boss Alarm Disc Lock 4.5 5 2 2
Good product not quite perfect I feel pretty safe with this thing. It'd be pretty hard to move it or the bike without setting off the alarm. Unfortunately I can barely hear the alarm through my window (my bike is parked within 10ft of my window). I wish it was louder, but it's probably enough to spook a thief. I've also had two or three false alarms in the month I've used it. Not a big deal. Overall I recommend it. And thank you Revzilla for your great customer service so far. You rock. January 21, 2016
Great, so far Heavy duty lock, the shackles are beefy but it just barely fits around a gap in my rotor. It's advertised as being extremely weather proof, it has rained a few times since I've got it and it still operates like nothing happened. It's very easy to use, simply line up the red arrow with the red sided shackle and it's armed. The alarm has a perfect amount of sensitivity for it to trigger. I have had Xena's in the past that have gave me nothing but problems, and they're alarms are extremely sensitive and even sound if they're is a slight breeze or if it rains. Overall a great lock so far, have had it for about two weeks so only time will tell how it continues to protect my bike. August 21, 2015
