I was disappointed to have to replace the whole aluminium surround and slider sides just of the sake of a new fabric mount. The deign has changed and the slide pieces are smaller than my installation since 2006, as is the aluminium front piece with the Velux badge on it.
Net Promoter Score is a loyalty metric used as a KPI for customer experience, measured on a scale of -100 to +100.
To calculate the NPS, we first ask customers to answer the question "How likely is it that you would recommend this company to a friend or colleague?" on a scale of 0 - 10.
Customers who answer 0 - 6 are Detractors, 7 - 8 are Passives and 9 - 10 are Promoters. The NPS is the sum of % of Promoters - % Detractors.
