These are excellent locks. Several people have noted not TSA approved, but every good hotel their has learned how to open the TSA approved locks. Yes that's what you need for checked luggage at the airport, but that's not what you want in your hotel room or if you've left your luggage with the porter. Outside of checking your bag with the airline you want one that is not TSA approved. That's why I bought these.

These locks are fairly small, but seem to be very strong. Setting your own code is easy and only takes moments. The only negative is that the numbers on the dials can be hard to read in indoor light as others have pointed out. Also, they are not TSA approved, meaning if you put these on the outside of your luggage TSA will not be able to open them to inspect them. This is a plus to me as I don't care to lock my luggage for transport on the plane. It's the need to put items in my luggage and lock it while it's stowed at the hotel that I'm concerned with. Dishonest staff all know the TSA codes and having locks like these keep them out of your bags.

All in all, these are an excellent choice for luggage locks. They're strong and sturdy (in the Master Lock tradition) and you get to set your own code to unlock them. I deducted only for the readability problem of the letters in indoor light. 4.5 stars.

Didn't have any problems with it locking up or the combo changing by itself. Used these on my backpack when I traveled to Europe to make sure Pick-pocketers didn't take stuff from my backpack.

We have many of these at the university that we use to seal computers instead of luggage. These are super easy to break into. If you lift the metal hook until it stops, you can literally "feel" the lock unlock when you switch to the right number (Starting from the bottom to the top). Bottom line is, these are fine when you have sight of your luggage or don't have anything too valuable in them. I wouldn't trust them for anything else. Also, with 10 minutes of free time, you can physically bend them until they break.

I used these locks to lock my suitcase and valuables away during my recent trip to Europe. They were easy to set up and worked perfectly fine. Even though they weren't TSA approved I didn't have an issue since I just placed them on once we were settled in our bed and breakfast.

Much harder to pick than those TSA locks...very sturdy. I use them on my carryon backpack after passing through security as an added level of protection.

For the money, these locks are ok. I couldn't see how they were supposed to be opened by TSA which the description implied that they could be. However, for keeping the suitcase locked in a hotel room they work just fine.
