The displayed average score is not only based on our own evaluations but in many cases also on reviews from external sources if they have been added to the profile. This way, for example, we can include Google's score in the calculation.
Calculation of the score
The rating is based on a 'Likert scale', in this case, consisting of 1 to 5 stars. The displayed score is the average of all ratings, with and without review text.
External sources
In addition to the score calculated with our own reviews, reviews from external platforms can also be included in the average score at ValuedShops. These reviews count equally in the average score. Thus, 100 reviews at ValuedShops (with an average of 4.5) and 100 reviews collected elsewhere (with an average of 4) lead to an average score of 4.25.

Beautiful young Dutch company. We previously had the c100. Now we have the c150, and many of the things we thought could be better have really improved. The service is also top-notch! There was something broken, and the device is designed in such a way that it can be repaired. That's quite sustainable.
