Rated 4 out of 5 by SecureIn207 from Seems sturdier than it feels at first touch It seems to have a little more plastic than I would like to see on a security safe, however the tubular key and combo setup are well designed and usage seems easy enough. There is a little more leeway in the combination dial than I would like, but I suppose when you get something at a discounted price, it is a little easier to understand any shortcomings. If you're looking for something secure but not too bulky, this gets the job done quite well. It is light enough for one person to haul around empty, so it would be a good idea to bolt it down with the provided bolts. I also installed a tap light that uses a sticky magnet to mount to the inside of the safe.

Rated 4 out of 5 by Mark fixed gear from Heavy, but manageable. I mostly like the capacity. X large. Room to grow. Tray is bonus. Door is nice. Dual lock is a nice touch. Electric keypad is a distraction from the real intention of a safe. Security. Batteries? Wires? This is a lure of a "coolness factor" for those who easily take bait. A good combination lock, with key, is the best method. Here's what I wish you would manufacture. Keep the safe looking great by all black. Charge extra $50.00 dollars and make the combination dial, lock mechanism, and handle out of steel. Keep the tray,maybe add one. That would definitely keep me a loyal customer. Thanks for listening.

Rated 4 out of 5 by McBob from Solid, strong safe, appears secure This safe is the perfect size for my important documents and other items that need to be securely stored. I reviewed many safes extensively, concerned for both flood protection/water infiltration and fire protection. Ultimately, this was my choice, which should serve my needs. It was easy to set in place (at 100 pounds). I chose not to bolt it to the floor since my home has a monitored alarm system. I was more concerned for water and fire damage. The combination/key set up works flawlessly.

Rated 4 out of 5 by Gpad69 from Good safe Great size to store important documents for security, fire & water protection. However, the safe I had delivered from Home Depot came with a dent on the side. I did not want to go through the exercise of returning and then replacing the safe - I am hoping that the fire and water protection has not been compromised! I do like the extra security of having a key besides the tumbler lock. I went this way since I had read that the digital locks can be rather easily overcome with the use of magnets. So I feel more secure with the tumbler/key combination. I also own another sentry safe which has been outstanding!

Rated 5 out of 5 by sabre360 from Better than I expected I read quite a few reviews about this safe and almost all the concerns regarded the plastic handle and the plastic dial. I really didn’t get the feeling that these are overly cheap or would break at a moments notice. I believe they will be fine. I played with it probably ten times before I ever put any belongings into it. For my use there is plenty of room. Standard documents lay flat front to back. I lik3 the shelf for smaller items. My advice, read all the materials that come with the safe, register your product online and store your combination there. Overall, I like it.

Rated 2 out of 5 by Tghg from Second Sentry Safe This is my 2nd Sentry Safe. After a couple of years of working perfect the safe would not open. It had a keypad and key. I had to bang on the safe door with a rubber mallet and it opened. I found this on the approach on the internet. I contacted customer service and no one got back to me. After opening the safe it would not lock again so I put it out for trash. I bought a new sentry safe with the old fashioned tumblers and keys. So far it works fine. Very disappointed with customer service. I bought sentry safe because of price and a discount from Home Depot.

Rated 4 out of 5 by Tinker from Good for small items, medium security Finding this safe good for protecting some small items and providing a convenient storage place. Makes those things easy to find and access. Not very secure against theft, even when bolted down. If somebody knows you have this safe, all they need is a good crowbar to lift it out and take it away. Plastic parts on front will be destroyed in case of a fire, and it is not clear how one would be able to open the charred mess. Finally, potential buyers should read the instruction manual first -- states clearly that you must pay attention to moisture buildup inside the safe. Also, you will see that the limits on fire loss insurance that is touted are minimal. If you really wnat insurance, you need to purchase it through homeowners, etc.

Rated 2 out of 5 by Jonikki from Safe Issues I purchased this safe about a month ago and when I got it I could lock and unlock it without a problem with my key. Now it's locked up and all my documents and personal things are locked and I can't access it. Its very distributing and I was furious. On top of all that you telling me I have to use the combination lock and that the key is extra lock security and i had to pay for a copy of the combination. Sounds very stupid because before it worked fine with just the key. This was the second safe I purchased from your company but will be the last.
