Rated 5 out of 5 by kpatton from Exellent Quality I got the 1.23 cu ft safe. It is the perfect size with enough storage room and still small enough to find a safe place to locate it. I also got SentrySafe because they are owned by Master Lock. Master locks are the only locks I trust. I like the dual locking mechanism. I got the model with the old-fashioned dial mechanism so that I don't have to worry about replacing batteries. The mechanism is very smooth and easy to use. I will not be bolting the safe to the floor to make sure the safe stays waterproof. I have not had the safe very long so I cannot speak to durability over time, but I am confident that the safe will perform well over time.

Rated 3 out of 5 by Basie from Fairly good safe, but too much pastic Metal from seems good, and supposedly fireproof and waterproof (within limits). A few problems: - securing to floor requires drilling holes, presumably this negates waterproofing - plastic parts! This is not the place to cheap out. The handle is soft plastic which feels like it could easily break off. Even the combination lock gears feel like plastic, which could wear out and make the safe unopenable. Furthermore, a fire would melt all that plastic, again making the safe unopenable. All of these parts should be made of metal. Plastic parts are the weak link here.

Rated 4 out of 5 by BLV1 from Finally ditched the rental box at the bank. Product delivered in good condition. Good packaging. Built well. I like the combination and key system. Wish the interior was just a little larger. Standard size documents in folders barely fit. A bought a drawer and placed it at the top. A nice add. Overall a good purchase. Met my immediate need at a fair price. However, too bad the inside dimensions are not just a couple of inches bigger in both directions. I guess I should have spent more money. Not excited about drilling holes thru the unit to lag to the floor. I understand the logic, but there must be a better solution than that.

Rated 5 out of 5 by Hawklis from Recommend It is bigger and heavier than I expected. Really like that it uses a combination plus the key. That makes it doubly secure. If someone does get the combination numbers they still have to have the key also to open. Makes it doubly secure. Thought it could go on the the desk under monitor but too big so goes on floor under an end table by desk. Easy to understand directions and to register. Glad I made the purchase. It also is well made. Very heavy had to use a hand truck to bring into house when delivered.

Rated 4 out of 5 by Cold fingers from Good sturdy safe! It’s heavy! I think it’s a good safe, I got mine through Amazon, it came with three dents in it, looked like some of the packing was missing, and the manual with the combination was locked inside! I contacted sentry safe by phone and after a security check the professional I talked with was able to give me the combination to access the safe, very nice and friendly person to deal with. And I was going to send it back but After contacting Amazon they gave me money off of the safe so I decided to keep it, Amazon was very good about the whole deal as well! Thanks!

Rated 4 out of 5 by DCHaize from Good Deal on a Good Product I found a good deal on this safe and, since I've been searching for a smallish safe, when I found this one - I bought it right away. The brand is well-known. I received it fairly quickly and, although it seemed quite robust overall, I was a little disappointed in the combination dial. It's made of thin, flimsy plastic. I'd have certainly paid a little more for a metal version. Also, the sound of the dial when turning is a bit annoying and cheap-sounding. I don't like the fact that I cannot change the combination but, at least there's a secondary keylock.

Rated 3 out of 5 by Disheartened1 from One major flaw. This would be an excellent safe if not for the fact it has a really cheaply made plastic handle. Sentry should project quality. The handle should be made of the highest quality material. In a fire the handle would be gone in an instant. What good is a safe if it can't be simply opened after a fire?

Rated 3 out of 5 by Longrangeshooter73 from Very basic safe - not for very important items. It will do the job I need it to (keep things fire safe by placing these inside my other, larger safe. However, as a freestanding safe, I would avoid this one. The hinges are wimpy - I could literally cut through them in about 5 seconds with cut-off wheel on my cordless angle grinder. The handle is crap, too, and feels like it would snap with any pressure applied. If you need a safe of any substantiality, this is not it. If you are looking for something that will keep things locked up and maybe give you some fire time, it should do.
