These are insanely easy to install with a drill. 2 screws per blind. BUT they aren't on brackets. They are screwed directly into frame. They add a very nice accent but DO NOT buy them for privacy or sun blocking. They are very similar to hanging sheers in a window. They do look nice, though and if that effect is what you are in the market for, these are for you.
The cords on these blinds weren't attached which renders them useless. I don't work in blind factory so I'm unfamiliar with the mechanics. Unfortunately they're non returnable for some reason not explained so I'm stuck with this garbage.
