I wish there was a way to offer separate star ratings for product quality vs product sizing (as advertised). I would give four stars for quality. I installed two of these on side-by-side windows and they installed easily and seem to be well made. However, I ordered a third for a single window which measured 34" wide. The website says the following regarding sizing:
"Sizing: Please order your exact window size for inside mounting. All blinds have a half-inch deduction in width." My window measured 34" in width, so I ordered 34" wide blinds, assuming they would be 33 1/2" wide as stated. The blinds are actually slightly over 34" wide, so they would not fit the window opening. Please keep this in mind if you are ordering blinds for inside mounting. The supplier needs to make a correction on the website.
