Run do not walk away from this product. Poor quality, poor workmanship and dated in appearance. The blinds are loud, ugly and arrived damaged. The blind that did work was loud, it squeaked with loud metalic sound with only one use. The large blind I ordered was heavy and required TWENTY holes to install. Do not suffer the frustration of long and difficult installation, even with experience putting up blinds. They are not worth a nickel. Do not buy these blinds they are not suitable for use in your home or any other structure.
