Heed the warnings!

I set the new combination. It worked fine twice. The third time it got stuck in my ibook. I had to cut it off. Do not buy this lock.
Do Not Buy! 2008-03-14
Heed the warnings from the reviewers that indicated "mysterious combination changes", especially if you own an Apple laptop! I bought this for my son to use in college and after one week of use he called to tell me that the combination no longer worked!!!!
Do not buy 2008-02-27
I just purchased the lock recently. The lock is very hard to put on and take off. Even with the right combination on you have to pull a bit hard at the cable. Which makes it pretty hard to take off. The price of the lock is cheap, but you are better off buying a more expensive one.
Lock and secure

For users that travels a lot 100% recomended most cases when you need leave your notebook in some conference room or room hotel.
Don't Buy "d 2008-01-06
on Jan.6,2008 I bought my son a "Defcon CL" combo cable lock. I brought it home ,picked a combination and tried it 3 times and it worked all 3 times!! I then went and put it on my son's computer and guess what? I can't get it off. I guess it changed the combination on it's own. WONDERFUL!!!!
I then read all the wonderful reviews about this lock. I hope there are people who will read this before they buy.
There is a newer model than the one in the photo: It's Great!

I travel with my notebook in my backpack. I have had three of these things. You have to read the instructions to set the combination correctly!
They all have worked well and they NEVER have changed the combination on me spontaneously!
The newer model has the same features but uses AAA bats and not a 9V which the old one used. It is thiner than the old model also. I like the blinking red light when ever I arm it. I run the cable through my zipper on my backpack and leave in strapped to the desk or chair in my hotel room. It creates a shrill LOUD alarm (if you set it for this feature) when the unit is moved. There are two sensitivities. You can set it to only alarm if the cable is cut. Yes you can cut the cable with a good set of wire cutters...so it would not stop anyone determined to take your notebook from you and had strong intentions to do so. It will stop someone from just grabbing it and trying to run.
I also really like the little gadget in the photo...(lower right hand corner of photo) it fits into the security hole of my notebook very snugly. The cable of the Defcon can go through the hole of this gadget and you can just lay it next to your notebook and it will start to "scream" as soon as the notebook is moved (it does give you a ~15 second warning before "screaming" with a loud CHIRP sound, so you can disarm it. Go to Targus website and check it out. I don't work for them. I do believe they sell a quality little alarm. It is not Fort Knox, it is a lot better than nothing. Blinking light and siren deters the common dumb criminal (not on drugs or really crazy)from taking your computer. It's should be just one of a series of methods you have to secure your notebook, not the only one.
It's nice for travel. You can even hang the thing on a door knob and know if someone opens the door. It's a motion alarm with a blinking red light. The number of blinks tells you how it is armed. I recommend it.
Mixed UP Reviews - Try This. 2008-06-06
Not one single review here is about the actual item for sale. When I clicked on the product reviews for this item. The item is the Targus PA460U DEFCON Authenticator - Black [Electronics] Which in fact has nothing to do with combination locks, cable locks, Or for that matter any kind of locking device other than a programed security device which locks down your computer so no one can enter your files without you being present. Unless of course they have the same finger print as you. It can also work for more than on computer at a time if for save you have two linked together in your network and prefer you children (example) or whomever to have acess to your computer when you are not present. All I can say is that mine works great and I very happy I have one.
Lock jammed, so I had to break it off 2008-06-02
I just finished breaking this lock off my laptop because it somehow jammed. My laptop was securely locked in my hotel room, keeping even a person with the combination from removing it. After a couple of quick blows with a ratchet handle, the lock itself broke apart. Once I took the end off the lock, it popped right off the laptop. See my photos above of the smashed lock.
When I bought this, I joked to my buddy that it would now take a thief 30 seconds longer to steal my laptop. If only I had realized how right I was. The only reason I spent half an hour trying to remove it was because I was trying to save the lock. I'll call the manufacturer to ask for a refund tomorrow. If they don't give me one, I'll take it back to Staples, where I bought this just six weeks ago.
Has anyone tried to simply break it off ?? 
2008-05-01
I bought a SIMILAR lock about 2 years ago. (It MAY have been this exact lock... it had 4 digit combo... and the name is very familiar... i just cannot say for sure) I was curious about whether a thief attempting to break it would succeed and also damage the slot. I gave it a quick twisting/bending motion with, i would say, less than 75% of my strength. I broke right off without damaging the slot !! It took 1 second. I M fairly strong... but c'mon! I am desperate for a real security solution but now have no confidence in this type of lock... unless someone can enlighten me as to how strong this item really is. Furthermore, most people (except the ones who actually cut the lock or the cable) here merely speculate that it's strong. I was in a hardware store looking at a (much thicker) 3/16th" galvanized twisted steel security cable. The workers there seemed to disagree on how EZ it would be to cut the cable with a simple pliers-like tool. The opinions ranged from "very easy" to fairly difficult. Not one thought very difficult.
Missing Features that are present in cheaper locks 2008-04-04
I'm using the cable for about a month now and haven't encountered (yet?) the dreaded "sudden change of lock combination" so many people here encountered. Yet, I am missing a feature that I had in a cheap clone lock looking almost similar to the Targus Defcon CL. See the black bulk that closes the cable loop ? On the clone it was actually a metalic disk with a hole (similar to the one you find in the laptop). This allows you to lock the cable to itself when going away with the laptop. You might think noone would steal a lock cable because they don't know the combination and would be useless, but it happens (especially because they get a better chance to steal your laptop later on). This forces you every time you need to walk away with your own laptop to have to carry the cable lock with you.
