Perfect Travel Companion – Master Lock Portable Lock Box Exceeds Expectations!
I recently purchased the Master Lock Portable Small Lock Box (Model: 5900D) in Gunmetal Grey, and it has quickly become my go-to travel accessory. This portable safe is incredibly functional, allowing me to set my own combination lock for added security.I used this lock box during my recent trip to Mexico at a resort, and it was a game-changer! I felt confident leaving my valuables safely tucked away while I enjoyed my time by the pool. The sturdy design and compact size made it easy to hang, and I loved that I could quickly access my items when needed.I've also used it stateside during the summer at various pools, and it continues to impress. The combination lock is easy to set and reset, ensuring that my belongings are always secure. I highly recommend the Master Lock Portable Lock Box to anyone looking for a reliable way to keep their valuables safe while traveling or enjoying outdoor activities.

Heavy duty with good storage and sleek design
This is a very sturdy case. It’s a little heavy - about 1 1/2 lbs. I’m impressed with the quality and the appearance is sleek. It’s easy to understand how to use it and the heavy duty cord is an added bonus for traveling situations. The interior is padded with foam so things inside don’t rattle when carrying it. It’s big enough to hold a phone and a wallet or a phone and a small pill bottle. It looks like it can take a beating without breaking open.

Good
Works well and keeps stuff safe on campus or on vacation. Wish it was slightly easier to use in the sense that the dials are extremely hard to turn but I guess that also makes it harder to break into. Overall- very good.

Compact, secure, and travel-friendly – A must-have for peace of mind
I’ve used the Master lock portable small lock box locally and on 2 trips, Vegas and Cancun, and I can confidently say it’s one of the smartest purchases I’ve made for protecting my valuables. Whether I’m on the go, at the gym, at the beach, or just need a secure place to stash items in my car, this lock box delivers outstanding performance, durability, and peace of mind. The customizable 4-digit combination lock is easy to set and eliminates the hassle of carrying or potentially losing a key. The locking mechanism feels solid and responsive, giving me confidence that once it’s locked, it’s truly secure. It’s strong enough to deter opportunistic theft and gives me assurance when leaving items unattended in public settings.Don’t be fooled by the term "small" — the interior space is very well-designed. I can comfortably fit my phone, passport, small wallet, keys, and even some jewelry with room to spare. The foam lining inside is a thoughtful touch that prevents my items from shifting around or getting scratched. It’s also a good size for securing medication if needed.This lock box truly shines in its versatility:Beach trips: I loop the cable around a beach chair or inside my beach bag. I can swim without constantly worrying about my phone or car keys being stolen.Hotel stays: Not every hotel has an in-room safe, and this box is a great portable alternative.Car security: I’ve used it to store cash or spare keys in my car when I don’t want to carry them into the gym or on a hike.Airbnb or shared living spaces: It adds an extra layer of security for valuables when you're staying somewhere unfamiliar.The included cable loop is extremely handy — it allows you to secure the box to a fixed object like a bed frame, chair, railing, or inside your trunk. It’s coated in plastic to avoid scratches but still strong enough to resist cutting or tampering. The outer shell is made of impact-resistant ABS plastic, and the internal foam padding protects delicate contents from damage. It’s also water-resistant, which is a big plus for beach or outdoor use. It’s not waterproof, so I wouldn’t submerge it, but it can definitely handle splashes and light rain without issue.This is an excellent all-around lock box for anyone who values security, portability, and peace of mind. Whether you’re a traveler, student, athlete, parent, or just someone who wants an extra layer of security in unpredictable environments, this product is a fantastic choice.Pros:Customizable combo lock – no key neededFoam-padded interior to protect contentsWater- and impact-resistant exteriorCompact but holds a surprising amountStrong cable for tethering to fixed objectsAffordable and well-builtCons:Not fireproof or waterproof (but not designed to be)Cable can be a little stiff at first useWould I buy it again? Absolutely. In fact, I’ve already ordered a second one as a gift!

Easy to use. It came in handy at the beach. Locked it around the beach chair while we were swimming. It kept my valuables safe & dry while we were enjoying the water. Very durable. Good value

OK Price, But Very Small & Made of Plastic
MasterLock calls this a "Portable Safe" in the ad title, but that's stretching it a bit. It's more like a portable locked box than a safe, by any stretch of the imagination. I like its looks & parts of its design, but I don't like the fact that it's made of plastic (polycarbonate?). Although the shell is hard, it's not likely to withstand a hammer, drill, or screwdriver the way that metal would.The box has a rubber-like covering over the four dial combination lock, to "increase weather resistance & conceal the dials from view", but after opening & closing this cover twice, it no longer closes firmly, leaving one side of it partially open (the top side). So much for "increasing weather resistance & conceal the dials from view". All four of the dials on the lock are difficult to roll to the combination & off the combination; they resist movement too much, & are made of plastic without a grip, or much of a detent. Other such locks are rubberized or textured for a better grip, or have deeper detents for a place to put a fingernail.I expected it to be small, but it's actual interior dimensions are smaller than I thought they would be. For example, to give you an idea of the size, you can fit only two boxes of standard cigarettes inside in any formation, & that's pretty small. It might be useful for jewelry, money, an important folded up piece of paper, or other small mementoes, but due to the ease of breaking it open & walking away with this, I wouldn't trust it for anything of real value.MasterLock's packaging leaves something to be desired. It comes in a neat looking, strudy box, with a fold open lid, like a book cover. When you open the lid, one side of this box is visible (the side with the metal design on it). After that, as far as I could tell, you have to rip the box open, not very elegant. A simple opening would be more appropriate. Then, under the lock box, the one-sheet, folded manual is taped to the inside of the box. To remove the tape from the manual (so I could unfold it), the entire front page of the manual was ripped off by the tape. A thoughtless design on the part of MasterLock.For the price, this is not a bad deal, if you have a use for it. It would seem to make a good choice for teaching a child about combination locks, security, & protecting their valuables. For adult usage, I have a hard time figuring out what it could effectively be used for, considering the very small interior & the plastic construction. If it were found in a car, attached underneath a car seat, a thief might do more damage to the car (trying to dislodge the box) than it would be worth to you, in terms of protecting what is inside the box.I also bought the The Club LB200 Personal Vault Security Lock Box, which I've found to cost only a few dollars more, but it is of much better construction & is a larger size, without being too large. The Club LB200 is a much better buy than is this MasterLock box.
