Targus PA410U DEFCON CL Notebook Computer Cable Lock Customer Reviews
Targus PA400U DEFCON 1 Ultra Notebook Computer Security System
-
I had this for approximately 2 years. It worked fine for couple of months but suddenely started to activate the alarm without any disturbances. One day I left my laptop attached the alarm in my office for about half an hour. During this period, the alarm was activated and I was embarrased to face my office workers. This is without increasing the sensitivity of the alarm. I sent it back to Targus and they were nice enough to give me a new alarm. But after several months, it started the same problem.
So, now I am afraid to use this security system with my laptop. But I did not face problems like changing the combination by its own. You can use it without the alarm activation (i.e: without batteries) but the cable is so thin, it is not recommended to protect any valubles.9/7/2006 12:00 AM | Rating:

Lock changes combination by itself - Do not buy
-
I have been using this lock for a few months without changing the combination. Suddenly I could no longer open it as it appears that the lock has changed its combination by itself.
I called engineering in the hotel I was staying in to help me. It took them less than a minute to cut the cable with ordinary pliers.9/3/2006 12:00 AM | Rating:

Once it's on it may never come off.

While I don't have any evidence to refute the package claim that it "attaches to any notebook",once attached to my son's computer it was almost impossible to remove.It took 10 minutes to get it off and we were pulling so hard I thought we would damage the computer.We will be returning it.Not recommended.

Combination mysteriously changed
-
I had been using the lock for my laptop for the past 4 months without any trouble. All of a sudden, today, as I went to pick up the lock, which had been left untouched in the open position overnight with my combination in it, it decided to change combinations by itself. So it was in the locked position but the combination is still the one I had set. I tried so many combinations 'around' mine but obviously there are so many different possibilites. The fact that I even have to try to think of what combination my lock decided to change itself to today makes this a lock I can't rely on!

Changing Combos
-
I am a student living in a dorm situation and so wanted some basic protection for my lap top computer.I purchased the defcon cl because it was inexpensive, widely availible, and easy to use.Unfortunately, it has one major drawback, occasionally it decides to change the number combinationss which unlock it.I went to the company website and they suggested trying the numbers immediately around the combination and if that failed trying all the number combinations possible (there are 10,000).Several hours, one blister, and 1787 combinations later, I got frustrated and used a jewelers saw to cut through the connection to my computer (this solution took only five minutes).I would not suggest this lock to anyone who lacks the patience to try trial and error experimentation until they reach the correct combination, nor anyone attending a school with a metalsmithing program.
