I have to say that this is a very cool product that intrigues me with its possibilities. It arrived in a very timely fashion with no defects or damage that I could ascertain and setting up the new combination was easy thanks to the included instructions. I was very impressed by the detail that went into making it look like a real book though after a few times opening and closing the lid, it started doing that thing I had read about where it doesn't close completely flat. The only workaround I could think of was to either stand it up or put something weighty on top of it to keep things in order. The interior was surprisingly roomy given the relative size but that didn't affect the product negatively in my opinion.
Other than that, I look forward to seeing what goodies I can hide in it. Suggestion: Consider lining the interior with a fabric or some other material that could lower the amount of rattling against the metal. I'm currently experimenting with some foam material to tone that down but again, not negatively affecting my opinion of the product.
