The most important criteria carry a heavier weighting because they affect other aspects of the service, i.e. could either drag down or elevate the entire product.
It would, for instance, be a deal-breaker if a card reader app is consistently buggy so you cannot accept cards at all. In this case, the service is useless even if the fees, contract, features, hardware and support are good. We therefore give a higher weighting to the reliability of the connected app than for, say, value-added services.
A higher weighting may be given to particular sub-points within the “Product” rating category, e.g. “reliability of app” gets a heavier weighting than “hardware design” within the same category. Only the Product category has more detailed sub-points to rate, as seen further down this page.
Given the sheer variety of product criteria, the weighting formula for each product category is not as strict as for the main 6 rating categories, but we try to give a measured Product score with some weighting in mind.
Consequently, we first determine a rating for the Product category based on our verdict of each sub-point. Then we calculate the overall review rating with the other categories added to the equation (Contract, Cost & Fees, etc.).
Example of how we might determine a Product category score:
