These blinds were super easy to install. The brackets can be installed either to the top or the back of the window frame & then the blinds just pop into the brackets (and out of, if you need to remove them). I've never had cordless blinds and was worried about how nicely they would stay put. They are great! You just push them up & pull them down and they always stay exactly where you put them. Without the cords, they look very tidy. I ordered 5 shades in 2 different orders & had 1 blind arrive defective and 1 arrive with a small plastic bit broken, but Overstock.com was very nice & fast about sending out replacements. Since errors are always possible, I care more about how a company handles them than whether or not they occur; and Overstock.com makes dealing with errors super stress-free.
