Dependable Master Lock
Color: Assorted Colors Size: 1 Pack
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. ... show more

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...
Color: Red Size: 1 Pack
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. ... show more

Works great!

I have used these for years at my kennel for the gates and they work great. They are very durable considering that they are used outside. I would highly recommend them and they are a great price.

These locks are awesome and very handy. They have the perfect size when you when you needed to be used for anything in a specific I love them. They barely weigh and they are small.

Hard to Read and Awkward to Use
Color: Assorted Colors Size: 1 Pack
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. ... show more

Good locker
Color: Black, Blue, Red, Silver Size: 4 Pack
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. ... show more

This is a good lock at a good price, but weird to use
Color: Assorted Colors Size: 1 Pack
This travel lock was a good value and it functions as designed. But I have to warn you that it works a bit different than other travel locks, and requires some getting used to. Had I known this lock was so strangely designed, I would have paid the extra $3 and gone for another brand. For one thing, the order of the three numbers in the combination are vertical (top to bottom) rather than horizontal. You have to get used to holding the lock vertically and entering in the combination this way. It can also be difficult to remember to line the numbers up with the tiny guide dots that are between the numbers. In a dark room, you may have trouble entering in your combination if you can't see where to line up the numbers. Finally, unlike every other travel lock -- and even unlike any other padlock in general -- the lock unlocks horizontally rather than vertically. Instead of pulling the locking cable out of the lock, you push it to the side. This is so completely counter-intuitive I still struggle with it. And combined with not always knowing where to line up the numbers, you may think you are entering in the wrong combination if you can't see what you are doing and can't see how to pull the cable to the side to unlock it. The lock is good quality and performs well. I hate to give something that is cheap and well-made a mediocre review. But it's just too awkward to use. Spend a couple extra bucks and get a normal travel lock. ... show more
