The Data availability infobox category shows the amount and quality of information that is publicly available about the device or technology in question. It may so happen that a device is seen as positive but a reader should be wary of the information availability is limited, i.e. the positive description stems from only one review. This category is differentiated in a four-item scale:
- None - Only the name or a rumour is known about the device or technology. It does not have an official on-line or other publicly accessible presentation. It's creators, developers, manufacturers or distributors refuse to speak about it publicly.
- Limited - The information about the device are limited to it's name, announcement date, web page, pictures. No other technical data are given. No third-party reviews is available.
- Fair - Additionally to the information above, in-depth technical details (resolution, sensors) are available as well. Other, non-technical aspects, such as price and the date of release (even if only planned) are included too. Reviews about the device or technology are available.
- Good - In addition to the previous categories, there are studies available about the device or technology in question. Although the number of studies is small and can not be deemed conclusive.
- Robust - Apart from the data sufficient for the previous categories, the device is also extensively researched. The research is peer-reviewed and publicly accessible.
