    Rated 1 out of 5 by AmazonT6331 from Poor battery spring equipment installed initially Previously, I owned a Sentry Safe for many, many years and never had a problem. When I received this current safe, the problem was immediate upon delivery to me and I have not been able to fix it. Specifically, the springs holding and securing the 4 batteries in the battery containment device are extremely weak and loose. One the batteries are installed, they will not allow battery power from the batteries to remain constant. I have to keep using the key to open the safe door. The keypad becomes useless I am planning to send the safe back to Amazon for replacement. If this problem is not fixed, I will request termination of the purchase for this device and seek a better product.

    Rated 3 out of 5 by Capt_K from Lucky it came with a key. Overall an ok safe for the price. I am lucky it came with a key, as the batteries for the electronic key pad are accessed from inside the safe door. Issue is, that the cover that holds the batteries in place has a gap between the cover and the batteries. This allows the batteries to move out of position just enough that they do not allow the keypad to work. (Even when closing the door as gently as humanly possible). My work around was to attach some foam packing to the inside of the battery cover which ensures the batteries stay in place, (even when the door is slammed in a fit of rage...…….I tested it to that level). This is the second model of safe I have purchased from this manufacturer, I expected better quality than that.

    Rated 3 out of 5 by Economist411 from Set up needs improvement Your initial combination should be something like 12345, so that the key would not be needed to initially open the safe. The plastic bag containing the instructions and keys should not be secured as is. Tape it to the side of the safe... much easier to open. Battery cover should be simplified. The latch is impractical since it made of plastic. It can easily break when attempting to open to replace the battery. Better if the key holder cover slides down over the opening. It doesn't need to be secure because if it's closed, you'll need the combination!

    Rated 2 out of 5 by ISafe from Solid Safe but Batteries Pop Out The overall construction of the safe is good, however there is no cover plate for the batteries (just the key hook plate that covers the batteries but it isn't snug). The batteries pop out of place constantly resulting in the need to open the safe with the key, which defeats the entire purpose of the keypad safe. I currently duct tape the batteries into place, which isn't ideal.

    Rated 5 out of 5 by Old shooter from Perfect for mutiple pistols My son bought the same model because it is perfect for pistols. I bought mine and have 6 pistols and other valuables inside, with plenty of room. It worked perfectly from day one and I have to have the backup key override because I never completely trust a digital lock. I rigged up a battery powered light inside, which helps these old eyes find what I want. Love the product.

    Rated 5 out of 5 by Erik D from Very Satisfied: Good quality for money spent This is the first safe that I have purchased. I think that for the money I spent...it is a good value. The safe seems well made. The door, handle and locking bolts all work good. The directions that were included were clear and accurate. I am satisfied with this purchase.

    Rated 4 out of 5 by bmidge21 from Almost 5 stars Really happy with the safe. Only problem is one of the shelf clips bend during delivery and I can’t find an identical clip. Because of this I can put one of the shelves in.
