Xena XX15 Disc Lock with Alarm
Great Lock, Finicky Alarm
The alarm itself is great. It's made of heavy duty metal. I've had my lock for a while and there are scuff marks from use plus wear and tear. However the metal isn't displaced from me being putting it in a mail box and retrieving it when I returned home. Also, it hasn't rusted (even around the scuffs). I've had the alarm since February 2014.
The alarm is loud. 120 dB is loud, not enough to burst eardrums, but enough to make you want to figure out how to make it stop or get away from it. It works fairly well when the IR line is actually broken. There is a sensor in the alarm itself that reads and arms when the IR line is broken (by the brake rotor) and you lock the lock with a key. The problem with this alarm is that if you have a gap in your rotors (supersport brakes), it might not arm the alarm properly. It'll still lock though.
I can't speak for other bikes, but I know that for the front brake rotor of a 2008-2015 R6, the alarm will NOT arm. So that was just another function that was advertised but I was unable to utilize it. Double check what other people are saying about the models or you're going to have a hard time trying to figure out how to arm it and break the IR beam to arm the alarm. The IR beam and sensor is about 1.5 cm away from the locking shaft.
You CAN (if you're really wanting to make it work) stick a piece of paper in the locking slot, break the beam that way, and force the alarm to arm. However, if the paper falls out in the middle of the night, all your neighbors are going to hate you.

Favorite new gadget
I live in St. Kitts, in the Caribbean. It's mostly ghetto here and I own one of like 3 CBR's on the island. So everywhere I go, I get shifty eyes and sketchy characters walking up and checking out the bike. With this lock, I sleep so much better at night. Loud as heck alarm, if you're close by; enough to scare off anyone trying to mess with your bike. Sexy finish, quality parts, takes half a second to install and sneaks into my tiny storage space under the back seat (with undertail exhaust that eliminates all the space back there) Highly recommend to all my friends. It seemed a little pricey at first, but then I thought that this would last me for years and years. Totally worth it in my mind.

Alarm inconsistent but the overall lock works
I bought this lock because of the alarm feature and the alarm works when it wants to. The instructions were unclear on how to arm and unarm the alarm of the lock, also the battery was a pain to install the first time. When I'm riding, the lock is in the tail of my bike and about a week ago from today (9-1-14) the alarm has been slowly going bad. It goes off when it's in my rear seat, and the actual alarm itself isn't as loud. The good news is that it's still a lock and it's hard to pick so the primary function is still there. However, if your buying this because of the added alarm feature, skip this product.

Easy to use, hefty, and loud
It installs easily. The "warning" beeps clearly let you know when it is armed or when it is about to go alarm. Definitely wear hearing protection if you are going to experiment with it. It was not clear to me in the description and this is my first disk alarm so I did not know it is intended for the front disk. I assumed it was for the rear. Knowing that, I probably could have used a slightly smaller one. Regardless, I am pleased. I did not rate durability because I have just bought it but it seems like it is built to last.

Works Well, but Cumbersome
I have purchased several Xena disk alarms over the last eight years. This new version is nice, but more difficult than past models to lock. Past models took a 1/4 turn of the key to lock / unlock, but this new version takes a 1/2 turn. If I cock my hand and get ready, it is doable, but if I forget to rotate my hand 1/2 turn the other direction before starting, then I do not have enough twist left in my wrist and I need to let go, untwist my wrist, then continue with the unlocking turn. During this time, the alarms goes off like a maniac and I go deaf. I liked the 1/4 turn better.

Good lock and alarm
Installing the battery was a painful experience. Per the instructions, you have 20 seconds to install it before the alarm sounds. Mine sounded immediately and every time I would just about have the thing screwed back, it would go off again.
Now that it's set up, it works perfectly and you quickly get used to removing it quickly to avoid the alarm. It is very loud when it goes off and definitely do its job. Won't deter seasoned thieves but it will let you know someone's messing with your bike if your within earshot.

A little tough to setup, but really makes you feel safe!
Alarm went off a couple times when setting it up which was quite unpleasant but once you have the battery in and it on your bike you feel really good.
I have this on a 2005 Yamaha Roadstar Warrior.

Does what its supposed to do.
I have been fortunate enough where i haven't had hear it go off. But it does the somewhat job of protecting my bike and keeping me somewhat at ease. Ultimately, you need multiple layers of security, this being one of them. its simple, feels like it's made of high quality material, and it fits. I've tested it myself a few times and yes, a good nudge will set off a warning that will turn into an ear-piercing siren.
It fit easily in my storage compartment and has been good for a few weeks now.
