Style Name:Combination Lock Cable
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.

Style Name:Combination Lock Cable
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!

Style Name:Combination Lock Cable
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.

Suddenly changes key
Do not buy unless you want to play "thieves and safes". I took about an hour to unlock my laptop and I arrived late to an important meeting.

Piece of CRAP
DO NOT WASTE YOUR MONEY. Bought this lock and it jammed and reset its combination! I had to drill through the lock to get it off and it ended up scraping the side of my laptop.
