    • Good little safe
Color: Gunmetal Grey Size: 9.8 x 5.5 x 2.6 inches
It worked well on vacation. I holds your valuables and it seems sturdy. I’m sure if it’s stolen, it could certainly be broken into. If you check bags, I recommend putting it in there and not on a carry on. It was the first time in over a decade that my bag was set aside for inspection because of how this safe looks in their x-ray scanner. ... show more

    • Strong and safe for valuables!
Color: Gunmetal Grey Size: 9.8 x 5.5 x 2.6 inches
Love this!! 5 stars (dunno why one won't light up) Easy to use and holds small valuables/money. It would have to be smashed with something very heavy to break into - I don't think it could be easily broken into, so it is definitely sturdy, strong and safe. Easily fits into my night table drawer. Small enough to pack into a suitcase for travel. Highly recommend! ... show more

    • Pretty good safe
Color: Gunmetal Grey Size: 9.8 x 5.5 x 2.6 inches
If a criminal wants your stuff inside, they will get it and this wouldn't work. This isn't Fort Knox...but if you're at a water park or amusement park, and wanna tether a small safe to a pole to put your keys or phone into...this is perfect (That's what I'm using it for). This is a pretty decent safe. The wire that connects to it is coated in plastic and pretty long. I really don't know if there's any metal in the safe to make it more difficult to break into. But I wouldn't use it for anything super valuable. But it's a decent item for under $20 ... show more

    • Great portable lock box
Color: Gunmetal Grey Size: 9.8 x 5.5 x 2.6 inches
I purchased this for a trip to Egypt. Was perfect for holding passports, cash, credit cards and jewelry I purchased. It doesn't hold alot but it's a perfect size for these smaller type items. I liked the cable rope to loop around the closet, but most times we had this with us. Easy to fit in carry on luggage or a book bag. One odd aspect I wasn't expecting was at the airport my carry-on was pulled aside for additional screening due to this item. A few minute delay but no issues once they saw what it was. ... show more

    • Compact, secure, and travel-friendly – A must-have for peace of mind
Color: Gunmetal Grey Size: 9.8 x 5.5 x 2.6 inches
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 needed Foam-padded interior to protect contents Water- and impact-resistant exterior Compact but holds a surprising amount Strong cable for tethering to fixed objects Affordable and well-built Cons: Not fireproof or waterproof (but not designed to be) Cable can be a little stiff at first use Would I buy it again? Absolutely. In fact, I’ve already ordered a second one as a gift! ... show more

    • OK Price, But Very Small & Made of Plastic
Color: Gunmetal Grey Size: 9.8 x 5.5 x 2.6 inches
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. ... show more
