Fitted as soon as arrived, easy to fit, the solar operation worked as indicated in the instructions. Seems a good operation in opening and closing, obviously can't comment on the reliability as its my first purchase of this type of blind, but happy with this purchase from Velux.
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.
