I was rather disappointed, as I'm in the middle of a trip overseas and was hoping to be able to contact the vendor without writing a review, to see if the problem can be corrected.  Unfortunately, it does not appear that Amazon offers this service, so I am reduced to writing this review.

I have been traveling for about 5 weeks and the three locks that I purchased were working perfectly until today, on a trip where I had just taken two of them along.  I was flying from Munich to Barcelona and was asked by security to open my carry on case, which was locked.  I was able to unlock it, and lock one of the loops, but the other loop would not lock.  When I arrived in Barcelona, got my luggage and went to the Tourist Office at the airport, I had to open my carry on as my hotel information was locked inside.  Though I had the correct combination, the lock would not open.  The Tourist Office then sent me to Customs, which directed me to another Terminal, where no one could help, and I finally returned to the original terminal and went to the Air Berlin Information Desk for help.  He informed me that if I had known the lock was defective BEFORE I came through the arrivals gate, one of the personnel there could have opened it; but once through the arrivals gate, you can not go back.  I explained my desperate need, as I had been running around for over an hour and did not even have the address of my guest house, as it was locked inside the case.  The man was good enough to offer to cut the lock - which he did, surprisingly with an ordinary pair of scissors.

Now I am torn about using the remaining two locks, wondering if they will fail and again leave me running around strange airports for hours.  .  I left one lock behind in the Munich apartment where I am staying and am left with only one working lock - and the fear that the combination will fail again.  I will have to buy another lock on the market here.

This is extremely disappointing and has colored my view of these locks - ordinary travel and after 5 weeks one suddenly doesn't work? I had read a review of someone who had this same experience, but not in the middle of a trip.

I am both disappointed in the failure of the lock and then concerned that an ordinary pair of scissors can cut through the wire loop.

I would appreciate hearing from the vendor about this.

UPDATE:  16 days later and on a Sunday, I'm getting ready to fly again on Monday.  The second of the three locks has now failed.  It won't lock on one side, and following the lead of the first failed lock, it will completely fail.  So here I am on a Sunday and flying out in the morning and another failed locked.  67% failure rate and it looks like I'll have to replace all three before this trip is done.
