Product I bought was Perfectfit blackout blinds. (>£100 each for what I would say is a small window). Installed them and the light leaks through the side of the perfect fit frame (measurements were correct). Contacted customer services, was told this is normal, the material is blackout but light leakage will always occur on the side of the blind... what's the point of blackout material if the light leaks out the side?. No offer of money back given its effectively useless and, to me miss-sold as blackout with light leakage down the side. Suggest looking else where for blackout if that's what you are after.
