Yes, I once accidentally reset my combination by moving the cable that resets it. You must learn to be careful which cable end you move to open this lock. I have an interesting bit of shocking info to share with all you travelers. Did you know someone can easily enter your luggage with a simple sharp object like a pen? Try Googling "open luggage pen" and watch the Youtube video. Eyepopper, no? Now you'll be like me and never trust any zippered luggage again. But you can't just throw them away. Just buy this LC cable lock. Put the long loop around the top handle and use the smaller loop to lock the main and front pocket zipper handles. The principle is the luggage handler won't fool with your luggae when he sees this because he will be unable to close the zippers if he can't move the zipper handles. Of course, this can be defeated if this uneducated bum has a TSA key or is a TSA agent. Truth be told a determined thief can jump on, kick, and slash your bag open with a sword or saw if he thought there was something to be gained inside your bag. That's what happened to me in the Bangkok airposrt recently. My bag was broken into upon arrival AND at departure. Nothing was stolen the first time, but a police telescoping baton was pilfered on departure. I googled "Bangkok airport theft" and there is indeed a history of luggage thefts at the new Suwanabhumi Airport even though security promised improvements 3 years ago! So be forewarned. Even more info if you google "Bangkok scams", "Thailand scams", and "Stickman Bangkok". In the end, just leave your valuables and nicest clothes behind. Travel with things you can afford to lose, and I promise you you'll be glad you have lots of room for the wonderful things you can buy cheaply there. A tip. Try going to Home Depot and make some 4 foot long cables with loops at the ends. String them through all your sleeves, pants, underwear, sandals, and lock them together. Thieves will steal all or none of the clothes. Don't forget to add a few can half filled with old peanuts with a note F.U.N. Monkeys love nuts.

Addenum: For those of you who experienced reset combinations and couldn't open your locks, you must be careful NOT to touch or move the RESET end of the cable after you open the lock. I learned this the hard way. I was in a hurry and must have inadvertantly reset it. Spent about 2 minutes of tachycardia before I luckily refound the wrong set of numbers. I am now taking THREE steps to insure it doesn't happen again. First, I painted yellow nail polish at two spot where I CAN move the cable ends. Do NOT move the RESET end. I think you can move the TSA end, but I will stay away from it. Second, I move only one number tumbler one or two numbers to left or right. For example, I will move the middle tumbler two numbers to the left and never touch the upper or lower ones. This way I can quickly open my lock even in the dark by feeling the middle tumbler and move it two numbers to the right. Hope this helps. Third, I always lock the lock when no using them between trips. When locked you cannot reset the combination. Beleive me, you forget details after a few months and mess up the combination.
