This safe is great quality, especially for the price! I was pleasantly surprised to see how much room it had inside. So many safes have a way smaller interior than they appear to.and that was not the case here. The safe is exactly as advertised in regards to size. I was able to fit my Ruger super redhawk .44cal that has a 9.5 inch barrel(14.5in total) on one of the top adjustable shelves and still plenty of room for other stuff. Removeable shelves are very easy to adjust, with a few possible configurations.It has 3 methods of unlocking; with a key, with a regular combination on the keypad, or if the internal batteries are dead, there is an electronic box that you plug into an input on the exterior of the keypad to power it and proceed with the combination. Very cool! Also has a quiet mode in case you need to access it in an emergency. The beeps it makes when entering combination are loud enough to matter.The lock bolts are very heavy duty, and when you shut the door and turn the lock knob, it very quickly locks automatically and stays locked until you proceed to use one of the three combination methods.The internal LED is not very helpful if you have the shelves installed, because it points directly at the center shelf and the top shelf and floor lighting is blocked. This is the only real downside I've found with this safe. I will be installing some extra lighting for more visibility, but I got some cheap battery powered LEDs from the dollar store that last forever, so no big problem there.As you can see in the pictures, I had room for a lot of valuables and home protection. This is a Christmas gift for my father and i think he will love it. Very happy with this purchase.
