Things I liked:The combination lock are very high contrast, easy to read, and give a noticeable positive response when turning them. Spring hinge holds the safe open so no fumbling with the lid Things I would have changed:I wish the metal was a bit thicker, the knob was metal instead of plastic, and the locking mechanism had a cover over it to protect the contents from accidental scratching when closing the safe. All part of the trade off of this price point. What others should know:The only airguns I can think of that would possibly fit in this are BB gun CO2 replicas of compact handguns. Do your homework and measure before you buy.
