Good Lock
One key will open all the 4 locks. This was convenient for me since I had 4 baggage and I had to carry 1 key only.
Good Value for Price
I bought these little locks for a recent vacation and they worked fine. All four locks can be opened by the same, TSA approved key, which makes digging through luggage a breeze. The only reason I didn't give this item 5 stars was because the locks are so puny, I have a feeling they can be busted easily. But for extra peace of mind they're great!
great for the money
These locks are great for the money. A couple of notes
1. A previous review mentioned that it's possible to unlock by pulling the shackle - I was a little concerned when I made the purchase - and I did a test immediately after I received mine - I stick in a screwdriver and tried my best to pull - nope it refused to unlock. Not sure if this is because of a different batch, but hopefully this can help some potential buyers make their decisions.
2. The keys and locks appear to identical, 1 key works for all locks. This is a plus for me as I don't need to worry if I lost a couple of keys(there are 8 in total). If you want more security, it would be minus.
Don't Bother
I wanted to secure items and not fumble for 4 different keys. I may or may not have ever used them on a commercial plane. I was swayed by the brand Master Lock....must have been a Master reject. The shank was so thin I could bend it with my hands and it was so limited in range that aside from minor applications they are useless to me! The photos make them look bigger and more imposing than they are in person. I should have known for the price but......
Well Built - Sharp Edges
These are well built brass locks, as other reviewers have pointed out. The overall quality is high, however, the edges of the lock are sharp and can damage leather luggage. With rounded edges, these locks would be a five-star item.
