“The word “review” and related words refer to the comparison of values that are freely available on the Internet. For comparisons on this domain, extensive data is collected, listed and analyzed in order to maintain the greatest possible objectivity.

In order to keep the number of subjective factors to a minimum, the real test of these products was not carried out because the individual tester would have played a too dominant role. Randi.io does not claim to have attended in any of the reviewed courses.

Comparison winners are determined on the basis of listed product characteristics in relation to the price-performance ratio. Customer ratings, on the other hand, were included where available, since the average of customer ratings allows a much more objective view than the own test.

The information and prices given are updated as often as possible. Unfortunately, mistakes can also happen here. Therefore the given information and prices can deviate from the actual information and prices in the shop.

Buy recommendations serve as tips and lead to the website of another company.

The choice of the compared products is left to the editorial staff and will be decided by chance (if not mentioned otherwise). In order to maintain neutrality, products from as many different companies as possible are compared. It is not possible to compare all products within a product category, as this would go beyond the scope of course comparisons.”
