This is a very nice item, and fairly priced. To give you an idea of the size...I can put my Kindle (different models) in it as long as I angle it from front to back. In addition to a Kindle, easily fits passport, wallet, a few watches, and other essential items. Could someone break into it? Sure, with enough time and the right tools. But then again, a few years back, I had a small wall safe bolted to an interior wall of a closet. A thief simply broke the wall around the safe and was able to remove the safe and carry it away. The instructions for setting the combination lock are easy to follow. It also comes with two keys. I purchased this for my car, but will be buying another soon for my home (though it would be easy to move the safe (it is portable!).
