Read any limits attached to a preview or demonstration opportunity. Consider aspects that cannot be assessed from the example alone.
Check whether older customer reviews refer to a different version. Check whether existing related items or arrangements remain suitable when that matters.
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.
