Posted on Jun 10 2014 - 12:33am by Susan Bewley

Disclosure: I received these products for free to review. The opinions in my review are honest and my own.


While I love to travel, there are some things that make it quite stressful, especially when you are traveling with small electronics, jewelry, and other items that might be a nice catch for thieves. When I am traveling with my husband for business and working out of a hotel room for a week to two weeks, it’s hard going without some of these things. The hardest part for me, oddly enough, is having enough trust to keep small, expensive items in the room. Yes, I can hide them in the suitcase, but that doesn’t seem like that much of a deterrent. Wouldn’t it be great if you had a tiny safe that you could throw in your bag or a drawer? Recently, I learned that Master Lock made the perfect thing for our traveling needs – the Master Lock Storage Security No. 5900D. After reading quite a bit about this safe online I couldn’t wait for it to arrive!

Master Lock Storage Security No. 5900D: What is It?

    I like that it not only locks itself – you can lock it to other stationary things! Very cool – and a good piece of mind when you are traveling.
    Sometimes those in-room “safes” don’t feel very safe.

    I like that you can set your own combination for the safe. And I like that it has access port for easy charging while keeping your items secure.

    My favorite feature of this device is the size. It would be something that could be taken with you to increase security of your items while traveling, or even in the car. What a great idea.

    I love how compact it is. Without taking up a lot of room, you can put the essentials in it. This way, everything is all together, and you don’t have to worry!

    I love this! We travel often with my kids sports teams and I worry about keeping important items with us at the stadiums/parks but don’t want to leave them in the car. This would be a perfect solution for us. Lightweight, portable and water resistant – just in case it rains.

      Oops. I forgot my second sentence. I also like that it is shock absorbent. That feature would come in handy around here. =)

    I really like that it is small. We travel frequently and hotels don’t always have safes or they aren’t free. This product would be perfect.

  9. Christina B. June 10, 2014 at 11:40 am - Reply

    what I love most is that the safe can be locked to something else. I would hate to put my stuff in it just to find someone was curious or didn’t realize it was a safe and ran off with the thing.

  10. sandra June 10, 2014 at 2:53 pm - Reply

    i like that it is a combination lock. and also that it can be attached to something else to secure it in place.

    This would have been perfect for me when I went to Hawaii alone. I had my tablet, phone, camera, etc. with me and it was hard to leave these things in the hotel room! Thank God nothing happened, but trust me, I didn’t have peace of mind. This seems like it would be perfect! I like how small it is, but still able to hold your valuables.

    This would be a great product to have while traveling! Wow, I really never thought of something like this. You can but travel documents or if you’re not going outside of the country, you can keep your jewelry locked up while swimming, etc. I also love that there’s a feature to lock the safe to something. What a great product!

    I’m impressed that it can hold an iPhone and other valuable items without being too bulky. This would be great to lock up to a bicycle!

    This little safe would be great to secure things while at the pool or something where you can’t take everything with you. It could hold your phone, keys, and some cash when needed.

    I like that it is portable and that it has a ear bud/charging cable access port, listen to music or charge devices while securely stored. I also love how it is water resistant so you can take it with you to places that may get a little wet but still be able to protect/bring your valuables.

I love that it can be secured to something and that it has a access hole for charging. How smart! Thanks for the chance to win one of these cool Master Lock safes.

    I like that you can set the code on the safe, so you don;t have to remember predetermined numbers. And I like that it is portable enough that you can take it when you travel different places.

    This would be ideal if you travel or whenever you go somewhere. I like to study at starbucks often. Whenever I use the bathroom, I don’t like to leave my things behind. Because of this, I always end up looking for another table to study in. This would be useful!

    I like it because you can store it almost anywhere because it’s so small, and i can tuck it under my pillow knowing no one can get my valuables

    the first thing I like about it is its appearance, which looks kinda swanky to me. don’t you agree/ the other thing is that its function. It actually locks stuff up.If I go to buy something like this, htat would be the most important feature. i definitely want one becaus i have lots of stuff i want to lock up.Although, I kinda wish the stuff I had to hide was money.

    This tiny storage security is quite useful. From the post I thought it something like a heavy equipment but I was surprises to see this kind of thing which provides good security and portable.
