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 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 1 out of 5 by XcaLi from Cheap Product and Lack of Custumer Service Purchased this safe and once set up found that the gears were broken not allowing the dial to turn counter clockwise. Contacted Sentry Safe about the issue weeks ago and have not had a response. Gears are apparently made of plastic as well as the safe handle.

Rated 4 out of 5 by jfitz from arrived with a dent in the side I believe the damage occured during shipment. It appears to be cosmetic and not functional so we didn't bother exchanging it. Other than the fact that it arrived damaged, I think it's a great safe. It's heavy and strong. I like that it requires both a key and combination to open.

Rated 4 out of 5 by DonnaJim83 from Strong and safe I reviewed several safes and glad I picked this one, I’m not great at combinations but tried a few times before I put my valuables in, I feel confident that my things are safe in this, it’s exactly how stayed and arrived very fast, thank you from an older person!

Rated 4 out of 5 by Leonard Turner from Itss size is good for the price I think i need to buy a small air tight capsule that i can place in the safe as Sentry in the explanations make me think that this unit is not what people think they are SAFE as its a SECURITY SAFE but i should not keep some items inside that are important.

Rated 5 out of 5 by southern comfort from STRONG, MADE WELL. FIRE AND WATER PROTECTION Think this safe is very sturdy. Very happy with it. Just the right size. There is just one thing: THE ARROW ON TOP SHOULD BE RED IN COLOR. Would make it much easier to accurately dial the combination. I have to use a flashlight to open it.

Rated 3 out of 5 by Not a Fan from Not the best The safe weighs in at 70 lbs, a bit heavy for 1 person to handle. The manual combination dial feels like it has fragile mechanisms. You can feel the tumblers. I would think a good thief would be able to open the safe.
