The customer services was very helpful on placing the order and helped me with measurements for a difficult and wide 3 part square bay window. However, I was not happy with the product. The rings stick and roll over each other when trying to draw curtains closed over the corners, Had a professional from Hillary's look at it when measuring up for curtains and they would never advise using that type of corner (said they should be flexible corners) on a bay window of my type and size. The poles had already been cut and therefore I am unable to return the product. Fairly unhappy as I may have to take it down as it is causing a lot of irritation to family members when drawing curtains. Aesthetically the product looks very nice, just not functional.
