Xena Security XN-15 Disc Alarm

This lock intimidates thieves.... I previously had a Kryptonite lock, without alarm, great lock, but the thieves had time to try to cut out the lock mechanism. They were unsuccessful, however I had to saw off the lock, which I was happy to do....I still have my Harley Davidson motorcycle due to my new Xena lock. Aloha, and God Bless you.

Over priced China made junk. Will never buy another. Six months the alarm quit working and after a year the security pin quit releasing.

Was great at first, very loud, then the honeymoon ended. The sensor lens gets dirty and this thing won't shut up even when securely locked in place and not moving. I ended up giving it away for free when I sold the bike I bought it for (I had other bikes, I was just sick of this thing). It wouldn't shut up, even in my backpack I could hear it screaming at stop lights. Thank god all you have to do to circumvent it is cover the speaker with your palm and it's hardly audible (quality security!)Piece of junk, buyer beware.

Just got the alarm a few weeks ago and I haven't been able to trigger the alarm. I've been using it with a bright orange cable, so it *looks* engaged to people, but the alarm doesn't sound if I start shaking/moving the wheel around. I'm hoping that it's just the battery that Xena put in the package, but that means I need to figure out the type of battery and buy a replacement.It seems like a durable/well-designed lock though...

The shipping was very quick. I feel like the smallest wind might activate the alarm but haven't tried it on my bike yet.Very loud and gets louder, i love that about it. Overall great product and awesome shipping!!!

This lock is hefty and seems to have all the possible angles covered to make the theft of a motorcycle more difficult. It would have been nice to have some kind of case come with the product to provide storage when not in use. I am a bit fussy when looking after my things.

Excellent. Alarm feature and 2 pounds chunk of solid steel is totally worth the extra twenty bucks. Lock and walk away. No worries. That bike isn't going anywhere. Stainless steel finish matched perfectly with my Silver Fury. Awesome product. GET THE DAMN LOCK.

This is a very good product. I have it on my bike whenever it is not in use, whether at home or on the road, and it performs flawlessly
