Don't buy; Flawed design allows accidental combination reset, then tears
on January 24, 2012
I bought one of these, which seemed nice. Then I bought another.
I read in the instructions about the risk of accidentally resetting the combination, and the manufacturer cautioned that there was no remedy for this. I didn't worry, cause I thought, "Only a dummy would do that, and I'm no dummy." Well guess what? Like some other posters, I accidentally reset my combination while normally applying the lock, and now I have to cut it off my computer.
By design, the combination is intended to be reset by twisting the cable in the lock body to enter reset mode, setting the tumblers to the desired numerals, then untwisting the cable. That seems sensible until you consider that, to engage the lock in the computer's slot, you must twist the lock body WITHOUT TWISTING THE CABLE. If the cable is resting on the table with the computer then there's not much risk. But if the cable is hanging off the table, then the cable's weight may be enough to hold the cable stationary while the lock body twists around it. If that happens, then you can accidentally reset the combination to an unknown value in a matter of seconds. I never noticed it until I tried to unlock, then I was horrified to discover what I'd done. Now I have to go after it with either a hack saw or a dremel.
This lock is a trap waiting to spring on you. I'd never recommend it or use it again without a pair of cutters on hand to cut the cable. Definitely wouldn't give it to my kids or anybody else. It seems to have nice workmanship, but the design is ridiculous.
Perhaps the only way to avoid this is to have two combinations in mind, so you'd have one combination that opens the lock, and a second combination that you set it to when it's locked to your computer, instead of randomly spinning the dials. In that way, I think if you did accidentally change the combination, you'd change it to your second set of numbers. The problem comes when you're unknowingly in reset mode, and you carelessly spin the dials to random numbers, which then become your new combination. So when you return, and spin the dials to your expected combination, you'll lose your new (undesired) combination for ever. Or else you could get in the habit of always noting the dialed numbers before you start dialing them to your expected combination, just in case the first set of numbers has accidentally become your actual combination.
