Great shades, easy to install and easy to operate.  Just what I needed on my 3 big kitchen windows to block some of that hot late afternoon sun that streams in without completely losing my view.  When they're open, it's a very clean look... you hardly notice they're even there.  When rolled down, they block a LOT of the heat and light but I can still look out and see my pool and backyard.  Great buy, great value, much cheaper than comparable items at big box stores (I've been shopping for these shades for 6 months!)
