Solid Lock with Easy Combo Setup
I bought this Master Lock for multiple rifle cases, and it does exactly what I need. Setting my own combination was quick and straightforward thanks to the clear instructions. Once set, the dials turn smoothly and feel solid. The build quality is solid for general use. It’s not meant for ultra-high security situations, but for luggage and rifle cases, it works perfectly (i.e., checks the compliance box for rifle cases in MA). I also like not having to carry a key around. Overall, reliable and convenient.

Secure Luggage Lock, User Friendly
These luggage locks work perfectly! I used these while traveling this summer, no issues whatsoever. A very strong, secure, lock. They are easy to attach to just about any size luggage, easy on and off, no issues at luggage check-in at the airport. I felt confident ordering, as these are the "Master" lock brand, and I was not disappointed!

Good, but hard to read
Works well for luggage and other instances, such as locker in hostels. Downside: it's hard to read the numbers due to light glare on the metal.

Reliable and Easy to Use – Perfect for Travel!
These Master Lock TSA-approved locks are exactly what I needed for travel peace of mind. Setting my own combination was quick and simple, and the instructions were very clear. The flexible cable shackle makes it easy to thread through zippers or awkward loops on luggage and backpacks. They feel sturdy and well-built, and I love that TSA agents can unlock them if needed without damaging the lock or my bag. I’ve used them on several trips now and they’ve held up great with no issues. Great value for a 2-pack, and the random color variety was a fun bonus. Highly recommend for anyone looking for secure, dependable travel locks!

Reliable product for travelers.
Purchased as a replacement to a couple older luggage locks made by Master Lock. These new locks work as consistent with our prior ones with the combination easy to use and durable. Cable on the lock is not an issue. Would recommend.

Works well for basic luggage security
I needed locks for two pieces of luggage, and these do the job. The flexible cable could probably be cut fairly easily, so I wouldn’t consider them high-security locks. I personally prefer traditional solid steel locks, but these were available at a reasonable price. The combination is easy to set and change, and I trust the brand. For deterring casual tampering and basic travel use, they work as expected.
