I would rate this shade a 4.5 because it looks so lovely. But, because some of the parts seem a little flimsy, including the material the shade is made of-it feels like a slightly thickened paper.  From the outside, the shadow gives the window a nice polished appearance.  My husband noticed how well the shade blacked out the sunshine. Hoping this will reflect a slight downtick in our energy bills!  I am delighted with this purchase. Wayfair? Would you refund me the difference of what it costs now on sale? Does it appear that I purchased it at a higher price?
