Honestly, I took a chance with these blinds. You never know if your own measurements are correct or whether you take into account of the header rail in the length or whether or not the manufacturer adds or subtracts an eighth or quarter of an inch here or there. I've owned six condos and two homes in my life and one of the first installations to do is window treatments. I took a chance on these are they were perfect in every way...... Seriously, this is not a canned review. The installation was a piece of cake. Four screws into the inside mount of the window that hold up the brackets. The header rail of the blind just clips right in. I would say the installation was 8 minutes each.
These blinds are so clean looking. There are no cords and the plastic tabs are a good idea to install to pull down or up these blinds. All nine of the blinds that I ordered 8 x 34" and 1 x 26" FIT PERFECTLY. It's like they were made for the condo. I am so please with all of them. The condo looks so finished and clean. Bravo.
