We have been bitterly disappointed with manual overhead blinds installed in 2023 that simply don't work properly, getting stuck often. There were problems from the start, and now Sanderson sent us a longer pole, which does not solve the issue at all (see the videos, one with their technician witnessing the fail in the background). Their technician visiting told us it was a mistake for them to have put in manual blinds as these should be motorised. We are under guarantee and offered to pay the difference for the upgrade but Sanderson refused, saying we'd have to pay the entire price again! They ignored an arbitration service request so we have sent them a letter before action, no answer. I expect will see them in the small claims court unless they read their reviews and are concerned about public image.
