## Before you buy

- The listing gives conflicting outer dimensions: 46 x 33.5 x 8 centimetres in the details and 43 x 32 x 10 cm in a feature description. Confirm which size applies before buying if fit is important. The stated 17.3-inch device limit is a size claim, not a guarantee that every device of that screen size will fit. The claimed protective coating is described as water resistant, not waterproof.

## A good fit for

- Commuters or office users who want separate laptop, tablet and document storage in one briefcase.
- Buyers who prefer a shoulder strap that can be removed and a sleeve for trolley-handle travel.

## Less suited to

- Anyone who needs confirmed measurements before choosing a close-fitting bag or case.
- Buyers who need a stated waterproof rating or protection against heavy rain.

## Customer feedback

Aggregate ratings lean positive, with most ratings in the five-star category, but a smaller share is spread across three- and one-star ratings. With no written customer feedback supplied, these figures do not explain what buyers liked or what prompted lower scores. Treat them as a limited indication of reception rather than evidence of fit, durability or water resistance.

## Frequently asked questions

### What size laptop does the listing say this briefcase can accommodate?
It gives a maximum compatible device size of 17.3 inches. Check your device's dimensions against the bag's internal fit, since screen size alone does not establish compatibility.
### Is the Guardit 3.0 waterproof?
The listing describes a protective coating that makes it water resistant. It does not claim a waterproof rating.
### What are the briefcase dimensions?
The details list 46 x 33.5 x 8 centimetres, while a feature description gives an outer size of 43 x 32 x 10 cm. The measurements are contradictory, so confirm the relevant size with the selected listing.
### Can the shoulder strap be removed?
Yes. The feature information describes the shoulder strap as adjustable and removable.
