Hey all, I just picked up a Xena disc alarm system this week, haven't had a chance to try it out on my bike yet, as I'm out of town. Does anyone have any experience with these things? I have a regular disc lock, but the idea of a combined alarm seems sensible. I stuck the battery in it to test it briefly, and it is very loud and piercing, as advertised! I'll put it on the bike Monday, and post my impressions.
