We were very disappointed in their customer service. When they came to measure the windows, they didn't bring any sample books and didn't offer any guidance or advice about the blinds themselves. We had to get sample books from another company. When we asked for advice about how wide to order blinds, they recommended only 1 centimeter of overlap on each side. As we have never bought blinds before, we took their recommendation. They did a great job installing the blinds, but they are way too narrow. The blackout blinds don't work because light creeps in the side, and our living room blinds have a gap between the side of the blind and the window opening, so we have had to tape paper to the wall to prevent the sun from coming in. We contacted the company to complain and they made a half-hearted attempt to solve the issue with the blackout blinds, but they didn't even respond to our complaint about the living room. We were very, very disappointed in our experience with them.
