Very disappointed that this blackout blind has not been modified (DKL P10 1100S). The blind seems to last only a few years before the friction cord mechanism seizes up. and attempts to open or close the blind damage the mechanism. My suspicion is that the mechanism is suitable only for smaller windows (where I've not had this problem).
