Dependable Master Lock
We got new luggage and realized we had lost the keys for the locks that we always used on our old suitcases. I wanted something that wouldn't require a key and felt like it was a little sturdier and this lock definitely ws that. Setting the combination was quite easy and looping the lock through the zipper pulls was very easy. These were a good price and actually cheaper on Amazon than if we had bought them in a physical store locally. We got two of these - one in silver and one in red. Master Lock has always been great quality and I highly recommend getting this brand over others.

Good locks, button is a bit stiff
Bought these for my trip. Changing the combination was a bit difficult at first because the reset button is hard to push, but it is not a big deal. They lock securely on the luggage zipper

Good - but buy more...
Very easy to set the combination and fit our filmgear pelicases very well. They withstand the rigours of travel - US and international - very well and I've never had one lost thru handling anywhere in the world. Sadly, TSA are not so rigorous at fitting them back on a case after checking - and they check our bags all the time. So I have to travel with several spares, preset to the combination. The red color stands out well and makes the padlock easier to find in a cramped hotel room during packing, when all the gear is scattered around the floor. In the past I've had types with rigid locks instead of this flexible cable type - they got knocked off the cases almost every trip - these ones can take a hit and have a little 'give' so withstand baggage handling much better. We travel every couple of weeks - so these have had a pretty good field test - most recently in Germany, Sweden, England, Spain, Denmark and Italy. No problems with security there either - so don't be put off for international travel where foreign versions of TSA don't have the access key. Just make sure you buy extras... UPDATE: So a year later - and still going strong - despite some very heavy use. No issues at all - and it's not often you can say that about anything these days. And to add to their international travels, these have now covered Canada, Australia, Switzerland, Holland as well. So good in fact that I have just bought more for extra cases.

Good locker
This lock is simple and convenient to use. I like that it comes in different colors, so it’s easy to choose one that matches your luggage. The flexible cable makes it easy to attach to different zipper types, and putting it on or taking it off is quick and hassle-free. Overall, it’s a good little lock for the price.

Simple to use
Easy to use and you can always change the code. I mainly used this as a deterrent and an extra step if someone wants to open my luggage. I'm sure the lock can be cut but it's an extra step in which a theif can get caught. Nice product.

Hard to Read and Awkward to Use
It is extremely difficult to read the numbers on this lock. The combination wheels are metal with recessed numbers, and the reflective surface catches the light, making the numbers very hard to see. I had three different people look at it, and all of us were basically guessing at the numbers. The wheels should be flat black with contrasting white numbers, like most other TSA locks. That would make the combination much easier to read. The lock also opens in a very awkward and unintuitive way. Between the poor visibility of the numbers and the awkward design, I would not recommend this lock. Avoid it.

Good Little Lock
I used it on my luggage a few times. While I don't know if it really worked, I wasn't missing anything from my luggage. The instructions were easy to follow, which made the lock easy to use.

Secure and flexible and easy to use
This is bendable and flexible and gets in the hard to reach places. I also found it very secure doing many trips interstate but also to Europe so highly recommend.

A QUALITY LOCK
Brilliant little padlock. Nice looking easy to set up and strong. Just used on a trip to Mexico after reading review about how good this lock is. It lived up to the review and we have decided to purchase two more .

Buen producto
Solo lo he usado para malera de equipaje, muy fácil de configurar la combinación que se desea, solo se deben leer bien las instrucciones y se le puede cambiar la clave fácilmente. El cable se ve muy resistente. El cuerpo del candado es de muy buen material. Y lo mejor es que es de los candados aprobados por la TSA así que se puede estar 100% seguro que no lo romperán en revisiones de aduana o seguridad.

Dosent close tight on zips.
The code dials are flimsy, Loops are quite large so zips can still be opened a bit. Otherwise they do the job.
