The product itself is great. The fitting instructions were poor. If I has actually followed them, I would have cut out the wrong part of the insulating block. It would help if you made it clear which side of the window the fitting needed to go.
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.
