Rank #8 in Best Safe 2026: The Box Weighs 1.87kg
Lucn Home Safe 8.5L, Fireproof and Waterproof Digital Steel Box
Price and rating as shown on Amazon when we collected them. Both change.
The Lucn is an 8.5-litre steel box for £23.44 with 4.4 stars from 330 ratings, and it claims to be fireproof and waterproof as well as secure.
It takes eighth because of the claims rather than the box: fireproofing is a tested specification with an insulation layer, and at £23.44 no standard is quoted. Its capacity is also given in cubic feet, where the rest of this ranking uses litres.
How those 330 ratings break down
An average hides its own shape. This is the spread behind the 4.4 stars.

Questions people ask
Is it really fireproof?
The listing says so and quotes no standard. Fire-rated safes have an insulating layer and a tested rating; at £23.44 treat the claim as unmeasured.
What does 0.3 cubic feet mean?
About 8.5 litres, the same capacity the title quotes in litres.
Will it survive water?
The listing claims waterproofing without a depth or duration.
Should I bolt it down?
Yes: it weighs little and can be carried otherwise.
Why is it eighth?
Because the box is ordinary and the three claims are not backed by a standard.
How many ratings does it have?
330 at the time of collection, averaging 4.4 stars, with 72 per cent five-star and 6 per cent one-star.
