These are nice shades and pretty simple to install except that the screws they come with are not real wood screws so when trying to start them in the hard wood of a window sill, it takes a lot of pressure.  Also, in the description of the shades it says "Trimmable: Yes" and in fact, they are NOT Trimmable.  For this matter, Wayfair is allowing me to return the ones I was going to trim with free shipping.  Other than those two issues, where they are installed at, I love them as they operate very easily and filter the light enough but not completely.  They also give a clean look to the room and are better than traditional blinds in my opinion.
