    Rated 1 out of 5 by Martmoose from This safe is not too safe. This safe is not too safe. I can quickly break in to it with a screw driver. The locking latch needs to be metel. Also, it is too heavy not to have handles on the sides or on the top. The inside is too narrow and is barrly wide enough for hanging folders. When I tried to register it I had a very hard time finding the Modle number and serial number. The lable was not installed on the front with this information. The hinge is also plastic and can easily break. I am not too happy with the engenering for this safe.

    Rated 5 out of 5 by Corn Country from Small but mighty Safe is great for important papers, coins, etc. Its a bit heavy though.

    Rated 5 out of 5 by DMD2 from Great Value; Great Safe I've bought two Sentry Safes, because of the value and the feeling of safety they bring for very important documents. The first I purchased many years ago, and the lock still functions very well. I bought the most recent due to the need for more safe storage, and have enjoyed it so far.

    Rated 5 out of 5 by Graham70 from Seems to be a strong and sturdy safe! We only just purchased this safe do to the fact that our home was broken into a few days ago, and who ever did it made off with our older model, along with everything on it. Hoping this one will be good or better than the last one. We like your products. They are well constructed.

    Rated 4 out of 5 by ghtester from Wrong key; good size I opened the box and put my files in. Everything fit inside with space for more stuff. I tried locking the file and the key would not turn. I contacted customer service and a new key is being sent. It was very disappointing. The quality assurance is very low

    Rated 4 out of 5 by janet123 from Perfect for Personal use This unit being fire and waterproof is perfect for personal use. I just wish the handle was not made out of plastic. I think it is will alright but I would have preferred a steel handle even if it would have cost a little more.
