If your window/wall/ceiling is perfectly square, then these will be fine. I bought one track for an 8' window and another for a 10' window. The places where the joints are don't allow very smooth transit of the wheel hooks. It slides better when I am closing the curtains as opposed to opening where the wheels have to push the adjacent one open. My biggest complaint is that the clips hang down a couple inches from the bottom of the rail. I will have to buy the tape they use to make Roman shades, sew that on at the appropriate height, then use the hooks instead of the clips. In all the photos on the website, the curtain is right at the top.

Love these. I had a funny size to cover and having the adjustability was perfect. They did not come with instructions but it wasn’t too difficult to figure out, otherwise I would have given this five stars. They work perfect.

The track is fine, I suppose. I am still currently installing it and I purchased 106 inch curtain tracks. As per the instructions, the ceiling mounts should be placed a maximum of 12 inches apart, and unfortunately I was only provided 6 cieling mounts, so I therefore was never provided enough. inches apart.

Love it! So easily installed and great for big windows.

Super user friendly and easy installation. Purchased twice now. Installed along the ceiling for a chic / hotel feeling with floor to ceiling drapes!
