Xena XX-6 Disc Lock with Alarm
I Bought Two!
I dropped my first one of these from a height and it hit my concrete floor hard. Somehow it was the perfect angle to break the lip part that the inner alarm cover clicks into. Without it the alarm won't work (as it wouldn't be seated properly), but the lock worked fine without it. I bought some metal epoxy and reconnected this little part, and it works better than ever. I let the company know, and they were very helpful - hopefully they'll take a look at this in the future. I wouldn't call it a design flaw necessarily.
The lock is easy to install and remove, and I use it on almost every ride. I don't think it would deter someone who really wanted the bike and had a plan - but it will presumably make it a bit more difficult to steal. I've since dropped both locks several times, with no effect. My only complaint would be I'd like the alarm to be a bit louder than 120db, but that's still quite loud and unnerving.

I've come to an understanding with my Xena lock after awhile. It is absolutely insanely sensitive on my bike unless I position it exactly at the 6 o'clock position through the right hole.
It took a few weeks of annoyance to my friends and neighbors before I finally figured it out and even now sometimes it still goes off for no apparent reason. I'm fairly certain it hates me. I would go with a different product if I was looking again.

Solid choice if the larger models don't fit your bike
I got the XX-6 because I wanted a lock that would fit my rear caliper, and since it's smaller (with smaller holes) the larger models don't fit. I like the solid cast construction and double-locking features of the larger models, but this one is pretty solid too and doesn't feel flimsy.
The alarm feature has worked well for me; I haven't had false alarm issues but it definitely goes off if you jostle it.

fits BMW r1200c
After measuring my front disc vent holes I was shocked to discover that this XX-6 model fits my 98 BMW r1200c. I guess this is because the beemer has dual front discs brakes, and so each one is smaller than what you'd find on other large bikes. For once the beemer accessory is cheaper! Much lighter and easier to carry with you than the big honking U-Lock that came with the bike. I've used it for a few weeks. No problems yet.

Simple and effective.
This product does as it advertises. Easy fitment and loud alarm that would deter thieves. Sensitivity also varies on the location of the alarm on your disc rotor so you don't get false alarms.
Highly recommended, cheap and easy way to protect your precious bike.

Cover your ears
This is a great product, the only thing I have issues with is knowing when it's going to go off while I'm trying to put it on and take it off. I'm sure this is just due to lack of familiarity with it but it'll wake the dead.

Decent protection if you don't want to invest in full alarm system
I got the Xena XX-6 before I committed to buying a Scorpio alarm, and I wish I had just gone all the way and gotten the Scorpio first. While the Xena works, I wasn't satisfied with it in two regards- 1) it is overly sensitive and would sometimes go off randomly, for example 20 seconds after I armed it and walked away from the bike. I'm sure my neighbors loved that. 2) the alarm element of it is not very rugged. Maybe I'm just clumsy, but I have occasionally dropped the XX-6 on the ground a few times while I have been unlocking my bike or bringing it and my bike cover over to it. None of the drops were from very high up, but they were enough to jar the alarm mechanism and to do some weird things to do, as sometimes the alarm wouldn't work at all and I'd have to take the battery out and put it back in to reset it.
The short of it for me is that while its a decent solution for a disc lock, I wouldn't want to rely on this alone for its alarm function as it is finicky, and doesn't seem very robust, especially considering that its pretty easy to cover the port where the alarm blares out of to muffle it significantly. I also noticed that I could hardly hear the alarm (when it would go off randomly), even when I was sitting on my back porch and within what I would have thought was an easy distance to hear the alarm.

Works very well, warn the neighbors
I bought two of these devices upon viewing the reviews from the Revzilla team, as well as comments from others.
The device fits the front and rear brake rotors of my 2013 Ninja 1000, and 2012 Vegas 8ball. The device is very sturdy, and loud -- will wake the neighbors when you test it, or mistakenly fumble for the keys when disarming it (read: practice, practice, practice). I still jump when I disarm it.
