Nothing ever installed so easily!  I had 8 hung in about 25 minutes.  These are truly a great purchase from quality vs. amount paid, ease of installation, look and actual use.  I will buy another 14 of these for my upstairs. 
Light is filtered not shut out completely, I bought 36x64, they were spot on in measurement.  There is a clear pull so you can open and close without dirtying the blind, its clear so it is not an eyesore.

Perfect, perfect blind for me.  

Pros: Ease of installation, quality of item and color
Cons: nothing, this is the perfect blind
