Non-contractual photos

The visuals on this page are supplied by the manufacturer. They are frequently produced for a whole range — not for the exact model you are viewing: what you see in the photo is never a promise of what is included.

No exchange, return or cancellation will be accepted on the grounds that something seen in a photo (accessory, port, colour, keyboard layout, packaging…) is not found on the delivered product. Only the specifications written on the page are binding for the order.

What the image does not guarantee:

  • Colour : one image often serves several colours, and the shade you see depends on studio lighting as much as on your screen settings; the colour sold is the one in the title and the specifications.
  • Props and accessories : the items shown around the product (cables, stands, decorative objects, content displayed on screen) are not included unless explicitly stated.
  • Packaging : boxes, labels and bundles change with the manufacturer's revisions: the packaging delivered may differ from the one in the photo.

What is binding: the product title, this page's technical specifications, the description and, when provided, the manufacturer's PDF datasheet available in the downloads.

The slightest doubt about a specification? Contact us before ordering and we will check for you.
