Comment: Overall I am happy with my purchase. It most certainly seems to be a deterent for any bike thieves out there. The alarm isn't quite as loud as I thought it would be, but I think I was expecting ear drum bursting volumes.
Xena XX-6 Disc Lock with Alarm.
Comment: I ordered the alarm and, as always, shipping was extremely fast.
When it arrived, I was pleasantly surprised to see how compact the lock/alarm was, yet easily fit over the disc (either front or back) of my Dyna.
The alarm is not obnoxiously loud, but clearly enough to draw unwanted attention to any would be bike thief.
I am extremely pleased and would recomend it to anyone.
