Review: More a theft deterrent lock box than a safe - The words portable & safe just don’t go together. Only by the loosest definition should this be called a safe. With that in mind I consider this to be a theft deterrent lock box. It’s not heavy enough or built like a tank to prevent thieves from walking off with it & my guess is a hammer & screwdriver might just pop it open. A small bolt cutter might make short order of the cable. So what good is it you ask? I worked in offices all my adult life. About once a year someone would report something small but valuable stolen from their desk (keys, sunglasses, cellphone, etc.) Or, you’re on vacation & things go missing from your room or at the beach. While many hotel rooms now have a safe in the closet, they’ve been reported as easily broken into with a secret code. With 2 small cord openings on both ends I can charge my cellphone while it’s locked inside this lockbox while I eat a meal & secured to an unmovable object in the hotel room without fear of the maid breaking into my personal info. With inside dimensions of 1.25” x 3.5” x 8.125” it’s big enough to hold a passport, jewelry, preciption bottle, money, etc. but not all at once. I’m not sure if there a steel shell but the outside is plastic. The cable is thicker then many bike cables. It’s water resistant (rain) but not waterproof or fireproof but for $18 on desertcart it’s a great buy.
Review: Perfect for my use - These are perfect for what I’m using them for. I got 2 of these. A white one for the bedroom and a gunmetal one for the kitchen. I am a care giver and in order to keep this person from getting into their daily pills, I put each morning and evening dose in 7 individual ez dose pill containers for morning and evening. I then put 7 each pill containers into the one in the bedroom for morning dose and 7 of each day in the evenings dose. This way they are locked up and this person cannot get to them. This works out great for me. These will actually hold up to 2 weeks worth of the ez dose pill containers if I needed them to. I also use one ez dose color for morning and a different color for evening. Also white master Lock container for morning pills (light for morning) and the gunmetal (dark for night) color for evening pills. As I said Perfect for what I use them for! 👍😁

## Questions & Answers

**Q: Would this hold about 10,000 cash. All one hundred bills?**
A: Forget the 10,000 how much monopoly money can it hold i don't want my family stealing from me when i go to the bathroom

**Q: What are interior dimensions?  Wondering if it would fit an ipad mini and kindle?**
A: No, it certainly would not hold a Kindle. I can close it with my car/house keys, my passport, my billfold and my Droid Razr cell phone inside, and maybe a couple of Krugerrands; that's about all. I just made some detailed measurements, and here's what I found:Height (maximum) 1.5", (minimum)1.0"Width at maximum height, 2.75"; at 1.0" height, 3.25""The ends are round and semi-circular; it could hold a narrow object 8.5" long, but the largest rectangular object would be about 6" long, 3" high, and 1" deep - roughly the size of a personal checkbook. I know this is a lot of answer. I hope it helps you, and anyone else who needs to know its inside dimensions.

**Q: Is the interior deep enough for 2 or 3 regular size prescription pill bottles?**
A: I just went and tried my prescription bottle in it and it fit.  My bottle is about 1.5-2 inches around and about 4 inches tall.  You could fit about 4 of them in there.  I hope this helps.

**Q: This is only waterproof, not fireproof or resistant?**
A: No small case like this, made out of anything, is fire resistant. small boxes have too little thermal inertia ie too much thermal transmission to be rated as fire proof or fire resistance. Anyone saying anything this size is fireproof is lying.

### ⭐⭐⭐⭐ Nice little safe for the beach.
*by D***H on June 21, 2019*

Purchased for traveling and am very happy with this little safe. On a recent vacation I put my cash and jewelry in it, in my carry on, to go through TSA. It's small enough to fit in my purse without taking up to much space and everything is safe and secure. I also look forward to using next time I'm at the beach/pool to keep my phone/cash safe when I'm away from my lounge chair in the water. I'm not convinced it would deter someone seriously motivated, but I'm more interested in a little peace of mind that I won't be the victim of a crime of opportunity. Setting the combination lock only takes a minute and is very easy. I only gave it 4 stars because I purchased the white safe and it arrived a little scuffed and dirty. Also, the interior of the safe is very small. I wish the padding on the inside was slightly smaller so I could fit 2 cell phones inside. For the price, however, I don't think you can beat this little safe.
