I am very impressed with the quality of the shades. Though this is for my own home, I am also a professional in the window shade industry so I am familiar with shades and installations. I suggest to anyone doing this themselves to really follow the instructions and call for help if needed. I did the measuring myself, on the inside mount shades I did run into some problems but managed to fix it. I suggest one pay the extra price for guaranteed to fit. Windows can vary in width from top to bottom so it is important to measure the top opening of the window ( as well as the bottom opening ) to ensure that the shade will fit properly. The one thing I did not like is that on the metal continuous cord, it is not continuous, the ball chain is connected with a connector. I have a tool that will allow me to connect the chain together without this connector so I can live with it, for now. All in all it is a great product and Blind Chalet is an excellent source for shades.
