I haven't had shades before and have never installed them so I was alittle nervous about it. I ordered the first set for my grandson's bedroom.  They were easy to install and looked great. I then decided to order some for my husbands office which also went up so easily.  SInce I was on a roll with them I ordered a set for the living room.  They filter the light but still allow some in.  I love the grey shade and so easy to use.
