How should I interpret a sample, preview, or demonstration of a product?

Read any limits attached to a preview or demonstration opportunity. Consider aspects that cannot be assessed from the example alone.

What should I check if a familiar product has a new name or version?

Check whether older customer reviews refer to a different version. Check whether existing related items or arrangements remain suitable when that matters.

How can I ask for product information in a format I can use?

Do not assume that every displayed example is fully described by its caption. Do not treat the absence of an alternative format as confirmation of a product feature.
