An unbolted safe is a strongbox with a handle for carrying it away · review
A small electronic safe with a three-to-eight digit code and two override keys, dimensioned by SINZUX at 23 × 17 × 17 cm (9.1 × 6.7 × 6.7 in) and designed to be mounted to a wall.
The conclusion Small, cheap, and only as good as the bolts. Put the override keys somewhere else entirely.
The most important sentence about any small safe is not on its specification sheet: a safe that is not fixed down is portable, and a portable safe is opened elsewhere at leisure.
This one is designed to be wall mounted, and doing so is not optional. Through the back, into masonry, with the supplied or better fixings. Unbolted, it weighs a few kilograms and leaves under an arm, and everything else about it — the eight-digit code, the ten thousand combinations — becomes irrelevant.
Two of them, and they open the safe completely without the code. That is sensible provision against a dead battery and a forgotten code, and it means the keys must live somewhere that is not the same house. A drawer in the next room defeats the entire purchase.
6.6 liters and 23 × 17 × 17 cm (9.1 × 6.7 × 6.7 in) externally, which means noticeably less internally once the steel and the door mechanism are subtracted. Passports, cash, jewelry and folded documents fit. An A4 folder lying flat does not.
No security grade, no fire rating. Where a manufacturer states neither, this page reports neither, and the safe should be read as a deterrent against opportunism rather than as certified protection. The listing nonetheless calls it “fireproof” and “waterproof”: with no rating and no duration, neither word describes anything you can check, and it is not a fire safe.
A wardrobe or cupboard with a solid wall behind it.

Somewhere that is not the house the safe is in, or at least not the room. They defeat the safe completely, so a set left in a drawer nearby means the code is decoration. A relative's house, a workplace, or a bank box is the right answer.
For passports, cash, jewelry and a few documents folded, yes. For an A4 folder lying flat, no — the internal dimension is smaller than the external one by the thickness of the steel and the door mechanism. Measure what you intend to put in it.
It is the whole thing. A 6.6-liter safe weighs a few kilograms and is carried away under one arm, to be opened somewhere quiet with an angle grinder. Bolted through the back into masonry, that route is closed. An unbolted small safe is a strongbox with a handle.
