    • Easy Setup and Use
Pattern Name: Lock
I bought this lock for work because we have lockers that aren't assigned and I need to keep a few personal items locked up while I am on the floor. I feel like my wallet, keys and ear buds are safe even though this is a relatively small lock. Using a code is much easier for me because I cannot keep keys with me while I am working. The combination was easy to set and change and I like that I can change the combination periodically. A couple of weeks ago I had brought a gift for a coworker and was able to change the combination on the lock so they could get their gift and then change it back afterwards. For my use this lock has been excellent and serves its purpose perfectly. ... show more

    • Great Lock, Used at Hostels in Europe
Pattern Name: Lock
Had a 2 week trip to Europe, visiting a bunch of different countries and cities. We stayed mostly at hostels and I used this lock for the entire trip. It's easy to set and I didn't have any problems with people stealing stuff. It fit for all the lockers at the hostels, and the length of the handle was really handy if the locker ring happened to be thick. It's just a basic lock so I can't say much for the safety of it, but the thing with locks is it's usually safe unless you happen to have bad luck and meet someone bad. ... show more

    • Decent lock for the price
Pattern Name: Lock
The only thing I don't like about this lock is that the actual unlock numbers are on the side rather than in front. Would be much easier to use on a locker if they were in front.

    • Great for my work locker
Pattern Name: Lock
Easy to change the combo to a custom number. The lock fits through my fairly small work locker so it keeps my valuables safe. The lock feels sturdy and well built.

    • Good Lock
Pattern Name: Lock
The lock came with the size exactly as described. I was able to use it for my travel bag zipper, it seems very good and more sturdy than TSA locks.

    • Reasonable Lock, Reasonable Price
Pattern Name: Lock
This lock is ok for sturdiness and it is nice you can set your combination you want. It is a little difficult to change the combination and it looks like someone could bust this lock without too much work.

    • It does what is expected.
Pattern Name: Lock
It works fairly well but It doesn't feel too solid.

    • A wee bit too small, but still good.
Pattern Name: Lock
Needed a small lightweight lock to bring with me to work and back home. Instructions are easy to follow, and you can set up your own 3 digit numbers. It's a little bit on the small side, so you may have to fiddle a bit to unhook it from the lockers, or try to search for it inside your pockets full of other miscellaneous items (like car keys, coins, wallet, pen, etc). ... show more
