It takes sixth because it is the best deal of the small safes: the cheapest, with the hardware that turns a carryable box into a fixed one, and 630 ratings at 4.4 stars behind it.

## Questions people ask

**Why do the bolts matter?**

Because a 2kg safe that is not bolted down can be picked up and carried away; the bolts are what make the steel relevant.

**Does it need batteries?**

No, it is a key lock.

**How big is it inside?**

6.6 litres, measuring 17 x 23 x 17cm outside.

**Is it fireproof?**

No, and the listing does not claim it is.

**Why is it sixth?**

It is the cheapest small safe here with the fixing hardware included, and a key lock rather than a keypad.

**How many ratings does it have?**

630 at the time of collection, averaging 4.4 stars, with 72 per cent five-star and 4 per cent one-star.
