Easily Decoded by Sight (No Skills or Tools Required)

Reviewed in the United States on August 19, 2019

Color: Gunmetal GreyVerified Purchase

Disappointed. I have owned several of these for some time now, and used to love them (for keeping my medicine bottles, and other small valuables safe while traveling, or when strangers are in my house).

But, I just found out that this “safe” can be opened within 16 seconds (without knowing the code) from a YouTube video uploaded today by LockingPickingLawyer—entitled: ‘[942] Decoded by Sight: Master Lock Personal “Safe” (Model 5900D)’.

Sadly, I was able to open each of mine exactly as shown in this video. The LockPickingLawyer is right, you can easily see the gap when you’ve scrolled to the correct number. It really doesn’t take ANY brainpower, skills or tools to break open! Really, really disappointed!

DO NOT BUY this product. It’s just not “safe”.

Cheap quality and not worth the price!

Reviewed in the United States on May 21, 2017

Color: Gunmetal GreyVerified Purchase

I have now purchased two of these for each of them to break within 2 months of being used! Very low quality hinge! $20 is a rip off for this! Quite frankly, with it being a "Master Lock" box, I would expect better, more sturdy construction, not thin, cheap plastic! I have attached a picture of what has happened to BOTH boxes within 2 months if anyone from corporate wants to know what I am talking about, but I doubt they will.....

A deterrent, not an impenetrable safe..

Reviewed in the United States on October 5, 2015

Color: Gunmetal GreyVerified Purchase

Firstly, if you are looking for an indestructible safe to hold large items, this is not the safe for you.

This safe work great as long as you use it for it's intended purpose. To keep your small valuables relatively secure while in a moderately safe environment. Example: Using it while on vacation to prevent room service from accidently "cleaning" your wallet or phone. Or, if you have small children around and want to keep them from your medicine, phone, etc.

Now, if you plan on attaching this portable safe to a light pole and storing your Rolex and Bentley keys in it while you go for a long walk in Central Park, well... you might be disappointed. The safe is heavy duty and would take some effort to pry open. But the body is plastic so this safe could be defeated with a pry bar or hammer.

Bottom line, this product is meant to be as a safeguard and deterrent, not an impenetrable safe. If you keep this in mind you will not be disappointed. I am glad that I purchased this safe and feel safer (no pun intended, well maybe) leaving items in my hotel room when heading down to the gym or breakfast.

If this review was at all helpful please do me a favor and click the "Yes" button below. Thank you.

Good Safe, Fading Numbers

Reviewed in the United States on July 13, 2017

Color: Gunmetal GreyVerified Purchase

Great Safe, for small items. Big, BIG drawback is that numbers have faded to the point of invisibility after less than 6 months. I have tried paint pens, white-out, everything that I can think of. Have settled on just marking the "1" with a power engraver, and counting from there.
If Master Lock set numbers in a groove, or used a better ink, problem solved. But what good is a combo lock if one can't read the combo?

TOTAL FALSE SENSE OF SECURITY

Reviewed in the United States on October 13, 2019

Color: Gunmetal GreyVerified Purchase

Well, this was exactly what I needed. It fit my items perfectly and seemed to be secure.
Until.... after about 3 months it started to get stuck. It wasn't unlocking or locking smoothly and became very difficult to get it open and close.
Around month 5, it became very annoying, so I contacted Master lock customer support. They sent me some how-to info / videos on how to maintenance so it would function better. And well, I never actually took time to follow the advice. Then almost (exactly) 6 months of ownership it locked up completely, and I couldn't unlock it, at all...... so...... I ended up breaking into it... and IT WAS INCREDIBLY EASY TO BREAK INTO. I did it quickly, with absolutely no force, using a metal fingernail file, while holding my napping son on my shoulder.... in like 8 seconds. AND leaving with no obvious signs that the safe was broke into. Only some very minimal scratches that I really had to look to find. Something I probably wouldn't have noticed without having knowledge of to begin with.

It's kind of like putting the signs in your front yard advertising that you have a home security system, but not actually having one... it's a front. It will probably discourage the honest crook, but won't really keep anyone from your valuables, if they want them.

Even for $15, it's a rip off. Very disappointed in such a big name brand. Shame on Master Lock. I'm pretty sure it'd more difficult to break into the little toy jewelry boxes.

Needless to say, I will be replacing my little safe with something else.

If you own mouse guns and are looking for a very compact cable lock combination lock case, that's thin, sturdy, padded and just basically works this is it. See pics. Enough said.

The media could not be loaded.

EDITED* I contacted master lock. They sent me one directly from them. And 3rd one was the charm. They said if you have an issue contact them directly. But please check yours before you use it.

I was so excited to get this little lock box for our trips to Maui. I can attach it to my chair put my keys and cell in it. It is perfect or so I though. I bought one and the cord would eject when it was locked. Uhmm not very safe someone can walk up push the button hard and walk off with the safe part to open later. I ordered a second one and I had the same issue. I’m not sure if this is just a bad batch, but if you have one double check it. See my video I am so disappointed.

Excelente caja de seguridad ofrece muy buenas características para su precio.

*La caja es de tamaño bueno para almacenar carteras y celulares por si las buscas realmente para usarla fuera.
*No había notado que incluye incrustado su cable de seguridad para atarlo a algo más, que para liberarlo se usa el mismo PIN de seguridad y un botón distinto al de la tapa ideal para dejarlo en un árbol o poste si estás en una alberca por ejemplo.
*Tiene una pequeña tapa de goma que oculta y protege los diales donde viene cuatro diales para el PIN de seguridad y un botón para abrir la tapa y otro para liberar el candado que tiene, en esta parte se observa que está hecha de metal.
*En mi caso dos de los cuatro diales se ponen duros en ocasiones aun cuando se intente girar con la uña en las hendiduras, estaré probando la caja y veré si es necesario un reemplazo.
*Algo que no me agrado es que la tapa no se mantiene abierta por si sola y no se puede cerrar si no está la combinación puesta.
*La caja dice ser a prueba de agua y es porque el interior es en goma algo que no había notado en el anuncio, lo cual ayuda también si quieres guardar una cámara o celular amortiguaría los golpes y evitaría el agua.
*Si piensan usar el puerto de carga/audífonos tengan en cuenta que esta pensado par cables pequeños o en lo posible planos.
*La forma de cambiar el PIN es sencilla pero complicada ya que debes mantener presionado un botón interior mientras girar los diales a la nueva configuración con cuidado de anotar que combinación tiene si se soltó por accidente.
*Para usarse como caja en exteriores dudo de su efectividad por que la bisagra se ve un poco desde fuera pero no se que tan resistente es realmente si se trata de abrir por la fuerza, en mi caso la usare en casa así que va perfecto.

En resumen va perfecto para usarse en casa o ciertos lugares donde la puedas encadenar y no depender de una llave para abrirla sino del PIN con la desventaja de que de olvidar el PIN debes probar las combinaciones hasta que abra.

The cord can be released even when locked !

Reviewed in Canada on February 21, 2020

Color: Gunmetal GreyVerified Purchase

I’ve bought multiple Master Lock products in the past, but I’ve never seen one of their product being so cheaply made. Probably if they would start building them back in the USA, it would be built better ! I’ve received the first one defective and the second one defective also. The problem was that the cord would eject even when it was locked. To me this is a big problem as someone can walk up, push the button hard and walk off with the safe part to open later. I ordered a second one and I had the same issue. If you have one double check it before thinking that this gadget is ”safe” to use.
