I bought a disc lock, minus the alarm based on the reviews. Of the more popular options, many users complained of frequent false alarms and I decide I have zero patience to deal with that...lol
I have a Xena - has motion-activated alarm that is INCREDIBLY loud!
Just watched a video of that ABUS device - that's supposed to be an ALARM???
With the XENA there is no way you want to be even close to it if it goes off - in your garage it painful!
