I fitted my replacement blind to a velux window fitted in 1993. By trial and error I found the blind fitted by pushing hard on to the existing mounts, not up as shown on the video. Otherwise it was fairly straightforward and the quality of the unit looks good - time will tell!
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.
